Stability, Control & Performance
Flight-mechanics engineering that makes an aircraft controllable and mission-capable — stability, control sizing and full performance assessment across the flight envelope.
Overview
Stability & control and performance turn a configuration into a flyable, mission-capable aircraft. Kesari assesses how the aircraft behaves and whether it meets its mission numbers.
Results support flight-control development and confirm that the configuration delivers the required range, endurance and manoeuvre.
What we support
Stability, control and performance assessment for new configurations and for existing aircraft under revision.

Where it fits in aircraft development
This service consumes aerodynamic and mass data and informs control-law development and flight-test planning — the bridge between aerodynamics and flying the aircraft.
Why Kesari
First-principles flight mechanics backed by aerodynamic data, with clear separation between analysis and flight-demonstrated behaviour.
