Job Summary

Roles and Responsibilities As a Flight Mechanics Engineer (verification and validation), the following work area and skill sets awaits you:

Responsibilities

• Aircraft Flight Mechanics & Dynamics: Test the 6-DOF nonlinear aircraft flight-dynamics models to their 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 analyse aerodynamic derivatives, stability derivatives, control derivatives, and propulsion characteristics. Perform longitudinal, lateral, and directional stability and controllability assessments. Analyse control-system performance, stability margins, actuator utilisation, and control authority. Run Software-in-the-Loop (SIL) and Hardware-in-the-Loop (HIL) iron-bird, and flight-test simulations. Compare simulation results against flight test or analytical data and generate reports. Design test cases, write test scripts and verification procedures etc..
• Modelling & Simulation: Develop and maintain testing environments using MATLAB/Simulink, Python, C/C++, or equivalent tools. Test and mature the 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. Evolve aircraft response characteristics such as Time constants, Natural frequencies, Control response, Hover and transition response etc. Develop and simulate failure, fault, and degraded-mode scenarios. Support FHA, FMEA, FTA, SSA, and system safety activities from a flight-dynamics perspective.
• Flight-Test & Data Analysis: Analyse flight-test data and correlate simulation predictions with actual aircraft behaviour. Investigate discrepancies between simulation, ground-test, and flight-test results.
• 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.
