Roles and Responsibilities

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

1. Aircraft Flight Mechanics & Dynamics

  • 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.

2. Modeling & Simulation

  • 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.

3. Aircraft Performance & Handling Qualities

  • 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.

  • Support FHA, FMEA, FTA, SSA, and system safety activities from a flight-dynamics perspective.

4. Flight-Test & Data Analysis

  • Support preparation of flight-test plans, test cards, and flight-test instrumentation requirements.
  • Analyze flight-test data and correlate simulation predictions with actual aircraft behavior.
  • Perform parameter identification and estimation of aerodynamic and dynamic characteristics from flight data.
  • Investigate discrepancies between simulation, ground-test, and flight-test results.

5. Certification & Technical Documentation

  • Support preparation of engineering analyses and compliance evidence as per certification requirements.
  • Prepare technical reports, analysis notes, model documentation, simulation reports, and verification evidence.
