Roles and Responsibilities

As a Flight Mechanics Engineer (Modeling and Simulation), the following work area and skill sets awaits you:

Develop and maintain 6-DOF nonlinear aircraft flight-dynamics models.
Develop mathematical models for aircraft rigid-body dynamics, aerodynamics, propulsion, actuators, landing gear, and environmental effects.
Perform aircraft trim, stability, control, and performance analyses across the flight envelope.
Determine and analyze aerodynamic derivatives, stability derivatives, control derivatives, and propulsion characteristics.
Perform longitudinal, lateral, and directional stability and controllability assessments.
Conduct performance studies including take-off, climb, cruise, descent, transition, hover/VTOL, range, endurance, and landing as applicable.
Develop flight-mechanics models and analysis required for flight-control-law development.
Generate trim points, linearised models, aerodynamic derivatives, and operating-point data for control-law design. Evolve gain scheduling, control allocation, control mixing, and mode-transition logic development.
Analyze control-system performance, stability margins, actuator utilization, and control authority.
Support SIL, MIL, PIL, HIL, iron-bird, and flight-test simulations.

Develop models at appropriate levels of fidelity ranging from conceptual/low-fidelity models to high-fidelity nonlinear simulations.
Develop and maintain simulation environments using MATLAB/Simulink, Python, C/C++, or equivalent tools.
Implement aircraft, propulsion, actuator, sensor, environment, and flight-control models.
Perform model correlation against wind-tunnel, component-test, ground-test, and flight-test data.
Establish model validation processes.

Perform aircraft performance analysis and establish aircraft performance databases.
Conduct handling-quality assessments and support development of handling-quality criteria.
Evaluate aircraft response characteristics such as Time constants, Natural frequencies, Control response, Hover and transition response etc.
Support development and analysis of flight-envelope boundaries.

Develop and simulate failure, fault, and degraded-mode scenarios.
