Level 2#
We have discussed Level 1 in great detail. As we have seen, Level 1 is relatively simple.
In Level 2, we see more flexibility and additional choices. You will be exposed to some simple Python code and see how Aviary establishes a problem from beginning to end. Each step is built upon the capabilities of Level 3. Users will be led to Level 3 in a natural way.
Level 2 is defined in the aviary/interface/methods_for_level1.py file and it has a single method run_aviary() with a few arguments. If you examine interface/level1.py you see that Level 1 prepares those arguments and then call run_aviary(). For aviary run_mission aircraft_for_bench_GwGm examples, those arguments are:
aircraft_filename:aircraft_for_bench_GwGmphase_info:phase_info(loaded fromaviary/interface/default_phase_info/gasp.py)optimizer:IPOPT(the default isNone)analysis_scheme:AnalysisScheme.COLLOCATION(the default)objective_type:None(default)record_filename:problem_history.db(the default)restart_filename:None(the default)max_iter: 50 (the default)
All the above arguments are straightforward except objective_type. Even though objective_type is None, it is not treated as None. In this scenario, the objective is set based on problem_type when using the GASP-based mission method, but not the FLOPS-based mission. There are three options for problem_type. Aviary has the following mapping when objective_type is not set by user and mission_method is EquationsOfMotion.TWO_DEGREES_OF_FREEDOM:
problem_type |
objective |
|---|---|
|
Mission.Objectives.FUEL |
|
Mission.Objectives.FUEL |
|
Mission.Objectives.RANGE |
In Aviary, problem_type is set to SIZING when it creates a vehicle (see create_vehicle). As you can see, since problem_type is SIZING by default in our case and we don’t manually alter this setting, Aviary set objective to Mission.Objectives.FUEL. We will discuss more options of objective_type later on.
Note
If you want to use a custom objective function, you can set any arbitrary variable to be the objective by directly calling the OpenMDAO add_objective method instead of using Aviary’s built-in add_objective() method.
In our onboarding runs, we want to limit the number of iterations to 1 so that they all run faster. As a result, we will not consider whether the optimization converges. So, we will have
`max_iter`: 1
Level 2 cannot be run via aviary command on the command line. Users must develop level 2 Python code. The good news is that the Python code is pretty small. You can follow the following steps in order (we do not include function arguments for simplicity):
prob = AviaryProblem()prob.load_inputs()prob.check_and_preprocess_inputs()prob.add_pre_mission_systems()prob.add_phases()prob.add_post_mission_systems()prob.link_phases()prob.add_driver()prob.add_design_variables()prob.add_objective()prob.setup()prob.set_initial_guesses()prob.run_aviary_problem()
In the rest of this page, we will show a few examples to demonstrate how level 2 runs these steps. We start from rebuilding aircraft_for_bench_GwGm model in great details.
Build level 2 for the same aircraft_for_bench_GwGm Model#
We create a level 2 Python script to reproduce the aircraft_for_bench_GwGm model run that was used as an example in the level 1 document (this time we won’t use the level 1 functionality). The methods listed above are defined in level 3 (namely, interface/methods_for_level2.py). You can run the code as follows:
from aviary.api import Aircraft, Mission
import aviary.api as av
from copy import deepcopy
# inputs that run_aviary() requires
aircraft_filename = "models/test_aircraft/aircraft_for_bench_GwGm.csv"
optimizer = "IPOPT"
analysis_scheme = av.AnalysisScheme.COLLOCATION
objective_type = None
record_filename = 'aviary_history.db'
restart_filename = None
max_iter = 0
phase_info = deepcopy(av.default_2DOF_phase_info)
# Build problem
prob = av.AviaryProblem(analysis_scheme)
# Load aircraft and options data from user
# Allow for user overrides here
prob.load_inputs(aircraft_filename, phase_info)
# Preprocess inputs
prob.check_and_preprocess_inputs()
# adds a pre-mission group (propulsion, geometry, aerodynamics, and mass)
prob.add_pre_mission_systems()
# adds a sequence of core mission phases.
prob.add_phases()
# adds a landing phase
prob.add_post_mission_systems()
# Link phases and variables
prob.link_phases()
# adds an optimizer to the driver
prob.add_driver(optimizer, max_iter=max_iter)
# adds relevant design variables
prob.add_design_variables()
# Load optimization problem formulation
# Detail which variables the optimizer can control
prob.add_objective(objective_type=objective_type)
# setup the problem
prob.setup()
# set initial guesses of states and controls variables
prob.set_initial_guesses()
# run the problem we just set up
prob.run_aviary_problem(record_filename, restart_filename=restart_filename)

/usr/share/miniconda/envs/test/lib/python3.12/site-packages/openmdao/core/driver.py:143: OMDeprecationWarning:boolean evaluation of DriverResult is temporarily implemented to mimick the previous `failed` return behavior of run_driver.
Use the `success` attribute of the returned DriverResult object to test for successful driver completion.
In this code, you do the same import as methods_for_level1.py does and set the values of all the arguments in run_aviary(). Now we will go through each line in detail to explain each step:
Dissection of level 2 for the same aircraft_for_bench_GwGm model#
All the methods of prob object (including its creation) are defined in level 3 (methods_for_level2.py). We now look at each of them.
We add other inputs that run_aviary() requires:
aircraft_filename = "models/test_aircraft/aircraft_for_bench_GwGm.csv"
optimizer = "IPOPT"
analysis_scheme = av.AnalysisScheme.COLLOCATION
objective_type = None
record_filename = 'aviary_history.db'
restart_filename = None
max_iter = 1
prob = av.AviaryProblem(analysis_scheme)
Several objects are initialized in this step:
self.model = om.Group()
self.pre_mission = PreMissionGroup()
self.post_mission = PostMissionGroup()
self.aviary_inputs = None
self.phase_info = phase_info
self.traj = None
self.analysis_scheme = analysis_scheme
self.pre_mission_info = self.phase_info.pop('pre_mission')
self.post_mission_info = self.phase_info.pop('post_mission')
phase_info is a user defined dictionary (in a Python file) that controls the profile of the mission to be simulated (e.g. climb, cruise, descent segments etc).
For analysis_scheme, the two options are: AnalysisScheme.COLLOCATION (default) and AnalysisScheme.SHOOTING which are defined and described in variables_info/enums.py`:
COLLOCATION uses the collocation method to optimize all points simultaneously.
SHOOTING is a forward in time integration method that simulates the trajectory.
In this onboarding document, only the COLLOCATION scheme will be discussed. The line
phase_info = deepcopy(av.default_2DOF_phase_info)
prob.load_inputs(aircraft_filename, phase_info)

is a function that has a few tasks:
Read aircraft deck file
aircraft_filenameRead phase info file
phase_infoBuild core subsystems
We have seen aircraft_filename file (a .csv file) in our level 1 examples. In level 1, we simply called it input file. An aircraft model can also be directly defined in Python, by setting up an AviaryValues object with the desired inputs and options normally found in an input file. That object can be provided in the place of aircraft_filename.
Engines are built by using aircraft:engine:data_file in the .csv file. For example in aircraft_for_bench_GwGm.csv file, we see:
aircraft:engine:data_file,models/engines/turbofan_28k.deck,unitless
So, aircraft:engine:data_file has value models/engines/turbofan_28k.deck,unitless. The top rows of engine deck file are:

Users can provide an EngineModel instance of their own to use in Aviary’s propulsion systems by adding it to engine_models.
Other subsystems, including mass, geometry, and aerodynamics, are set up according to which legacy code options the user has specified in their input file, using settings:equations_of_motion and settings:mass_method. Aerodynamics is set up to match the selected equations of motion, while geometry will use either GASP, FLOPS, or both methods as required to calculate all values needed by other subsystems.
Next we check the user-provided inputs:
prob.check_and_preprocess_inputs()
/home/runner/work/Aviary/Aviary/aviary/utils/preprocessors.py:272: UserWarning: Mount location for engines of type <turbofan_23k_1> not specified. Wing-mounted engines are assumed.
warnings.warn(
This method checks the user-supplied input values for any potential problems. These problems include variable names that are not recognized in Aviary, conflicting options or values, or units mismatching.
Next, we add pre-mission systems:
prob.add_pre_mission_systems()
This call adds a pre-mission group which includes propulsion, geometry, aerodynamics, and mass subsystems.
For height_energy missions, aviary currently models FLOPS’ “simplified” takeoff as defined in mission/flops_based/phases/simplified_takeoff.py.
Next is the line
prob.add_phases()
Show code cell output
<dymos.trajectory.trajectory.Trajectory at 0x7f273954bda0>
which adds a sequence of core mission phases. In addition, if mission_method is 2dof and ascent is a phase, it adds an equality constraint to the problem to ensure that the TAS at the end of the groundroll phase is equal to the rotation velocity at the start of the rotation phase (_add_groundroll_eq_constraint(phase)). If mission_method is height_energy, it sets up trajectory parameters by calling setup_trajectory_params(). If mission_method is solved, it has a block of code to make sure that the trajectory is smooth by applying boundary constraints between phases (e.g. fuselage pitch angle or true airspeed).
It follows by adding post-mission subsystems:
prob.add_post_mission_systems()
Similar to pre-mission, it adds a landing phase if include_landing key of post_mission has value of True. If user chooses to define a post_mission, it will override the default. For 2dof missions, landing is defined in mission/gasp_based/ode/landing_ode.py. For simple mission, landing means a simplified landing. Note that the solved method currently doesn’t have any post mission systems.
The next line is
prob.link_phases()
This is important for allowing each phase of flight to pass to the next without discontinuities in the parameters. Consider Dymos’ Aircraft Balanced Field Length Calculation example. In that example, we see separate nonlinear boundary constraints, nonlinear path constraints, and phase continuity constraints between phases. We don’t want to go deeper in this function call, but just point out that each individual link can be set via dymos function link_phases. See dymos API for more details.
The code blocks in this function (namely, link_phases()) are for 2DOF, simple, and solved missions. The links are set up based on physical principals (e.g. you can’t have instantaneous changes in mass, velocity, position etc.). Special care is required if the user selects a different or unusual set of phases.
Now, our aircraft and the mission are fully defined. We are ready to define an optimization problem. This is achieved by adding an optimization driver, adding design variables, and an objective.
For add_driver function, we accept use_coloring=None. Coloring is a technique that OpenMDAO uses to compute partial derivatives efficiently. This will become important later.
prob.add_driver(optimizer, max_iter=max_iter)
Drivers available for use in Aviary are SLSQP, SNOPT, and IPOPT. The table below summarizes the basic setting along with sample values (the settings are options required by each optimizer):
Optimizers |
Drivers |
Settings |
|---|---|---|
|
om.pyOptSparseDriver() |
|
|
om.pyOptSparseDriver() |
|
|
om.ScipyOptimizeDriver() |
|
Note that SLSQP is freely available, but its performance is not as good as SNOPT and IPOPT sometimes. SNOPT is a commercial optimizer, but it is free for academic use. IPOPT is an open-source optimizer and it is free for all users.
Design variables (and constraints) are set in the line prob.add_design_variables():
prob.add_design_variables()
For default HEIGHT_ENERGY mission model, it is relatively simple:
Design Variables |

|---|---|---|---|---|
Mission.Design.GROSS_MASS |
100.e3 |

For default TWO_DEGREES_OF_FREEDOM mission model, the design variables and constraints depend on the type of problems (SIZING, ALTERNATE, or FALLOUT, see ProblemType class in aviary/variable_info/enums.py for details). First, there are four common design variables and two common constraints. There are two more design variables and two constraints for sizing problem.

In the above table, there are two hard-coded design variables: tau_gear and tau_flaps. They represent fractions of ascent time to start gear retraction and flaps retraction. There are two hard-coded constraints: h_fit.h_init_gear and h_fit.h_init_flaps. They are the altitudes of initial gear retraction and initial flaps retraction. The underscore in number “175_000” is for readability only.
There are other constraints using OpenMDAO’s EQConstraintComp component. We will not go into the details as this part is complicated and needs special attention. Note that each subsystem (for example engine model) might have their own design variables (think, for example, sizing the engine). Aviary goes through all subsystems and adds appropriate design variables.
You can override all the functions in level 3. So, you can set up your constraints in level 3 if the above ones do not meet your requirements.
The optimization objective is added to the problem by this line:
prob.add_objective(objective_type=objective_type)
The selection of objective is a little complicated.
Earlier in this page, we have discussed the objective when objective_type=None and mission_method is 2DOF. Let us discuss the other situations.
There are several objective types that users can choose: mass, hybrid_objective, fuel_burned, and fuel.
objective_type |
objective |
|---|---|
mass |
|
hybrid_objective |
|
fuel_burned |
|
fuel |

As listed in the above, if objective_type="mass", the objective is the final value of Dynamic.Mission.MASS at the end of the mission.
If objective_type="fuel", the objective is the Mission.Objectives.FUEL.
There is a special objective type: hybrid_objective. When objective_type="hybrid_objective", the objective is a mix of minimizing fuel burn and minimizing the mission duration:
obj = -final_mass / {takeoff_mass} + final_time / 5.
This is because if we just minimized fuel burn then the optimizer would probably fly the plane slowly to save fuel, but we actually care about some mix of minimizing fuel burn while providing a reasonable travel time for the passengers. This leads to the hybrid_objective which seeks to minimize a combination of those two objectives. final_time is the duration of the full mission and is usually in the range of hours. So, the denominator 5. means 5 hours. That’s just a value to scale the final_time variable. Since it’s a composite objective we didn’t want to have OpenMDAO do the scaling because the two variables in the objective are of a different order of magnitude. We will show an example of this objective type in level 2 discussion.
If objective_type=None for a 2DOF mission, Aviary will choose the objective based on mission_method and problem_type. We have discussed this case earlier in this page.
If objective_type=None for a FLOPS mission method, Aviary adds a fuel_burned objective. In fact, this objective is available for FLOPS mission only. That number you get is for the actual fuel burned in lbm. You may get something like fuel_burned with the scaled value [3.91228276], reference value 1e+04. It translates to the dimensional physical quantity of 39,122.8276 lbm. To see this in action, check the resulting reports/opt_report.html file to see the optimal results.
Note: Aviary variable Mission.Objectives.FUEL when using the GASP-based mission is actually a hybrid objective defined as
reg_objective = overall_fuel/10000 + ascent_duration/30.
where overall_fuel has the unit of lbm and ascent_duration has the unit of seconds. In our case, settings:equations_of_motion = 2DOF, the final value of objective is [5.5910123], with ref: 1.0 and units: blank. The units should be interpreted as unitless.
Here, ref is the reference value. For different objectives, the range may vary significantly different. We want to normalize the value. Ideally, users should choose ref such that the objective is in the range of (0,1). This is required by optimizer.
Note: Unfortunately, not all objective_type and mission_method combinations work.

This is a lightly wrapped OpenMDAO setup() method for the problem. It allows us to do pre- and post-setup changes, like adding calls to set_input_defaults and do some simple set_vals if needed.
If we look at the signature of setup() in OpenMDAO’s Problem class, we find that the available kwargs are: check, logger, mode, force_alloc_complex, distributed_vector_class, local_vector_class, and derivatives. The ones that Aviary uses are check and force_alloc_complex. Argument check is a flag to determine default checks are performed. Default checks are: ‘auto_ivc_warnings’, comp_has_no_outputs’, ‘dup_inputs’, ‘missing_recorders’, ‘out_of_order’, ‘solvers’, ‘system’, ‘unserializable_options’.
If force_alloc_complex is true, sufficient memory will be allocated to allow nonlinear vectors to store complex values while operating under complex step. For our example, we don’t use any of them.
For optimization problems, initial guesses are important.
prob.set_initial_guesses()
For solved_2DOF and 2DOF missions, this method performs several calls to set_val on the trajectory for states and controls to seed the problem with reasonable initial guesses using initial_guesses within corresponding phases (e.g. default_flops_phases.py and default_gasp_phases.py). For solved_2DOF missions, it performs similar tasks but for hard-coded state parameters. This is reasonable because a solved_2DOF mission is actually a level 3 Aviary approach. We will cover it in level 3 onboarding doc in the next page. Note that initial guesses for all phases are especially important for collocation methods.
The last line is to run the problem we just set up:

/usr/share/miniconda/envs/test/lib/python3.12/site-packages/openmdao/core/driver.py:143: OMDeprecationWarning:boolean evaluation of DriverResult is temporarily implemented to mimick the previous `failed` return behavior of run_driver.
Use the `success` attribute of the returned DriverResult object to test for successful driver completion.
This is a simple wrapper of Dymos’ run_problem() function. It allows the users to provide record_filename, restart_filename, suppress_solver_print, and run_driver. In our case, record_filename is changed to aviary_history.db and restart_filename is set to None. The rest of the arguments take default values. If a restart file name is provided, aviary (or dymos) will load the states, controls, and parameters as given in the provided case as the initial guess for the next run. We have discussed the .db file in level 1 onboarding doc and will discuss how to use it to generate useful output in level 3 onboarding doc.
Finally, we can add a few print statements for the variables that we are interested:

prob.get_val(Mission.Objectives.FUEL, units='unitless'))

As you see, there is a single phase cruise, no takeoff, no landing. Note that we must set include_takeoff to False because Aviary internally tries to connect takeoff to climb phase which we don’t provide. There should be a check to see if both takeoff and climb phase exist first. Aviary still has many things to be improved.
We will see more details for what users can do in level 3.
Level 2 is where you can integrate user-defined external subsystems, which is one of the main features of the Aviary tool. Examples of external subsystems are: acoustics, battery modeling, etc.
Assume that you already have an external subsystem that you want to incorporate it into your model. We show how to add external subsystems via external_subsystems key in phase_info.
We will cover external subsystems in details in Models with External Subsystems page.
Summary#
As you see, level 2 is more flexible than level 1. In level 2, you can:
add/remove pre-defined mission phases (via
phase_info, see example above);scale design variables (via reference value in
phase_info)import additional files (e.g.
aero_data_file);set pre-defined objective (e.g.
hybrid_objective);add external subsystems (via
phase_info);set
use_coloring(see example above).
Most Aviary users should be well-served by Level 2; we have purposefully constructed it to be capable of most all use cases, even those on the forefront of research in aircraft design.
That being said, there are some cases where Level 2 is not sufficient and you may need additional flexibility. We are ready to move on to Level 3.
