Flight Dynamics

Stark/AMI maintains a suite of methods for flight dynamics prediction and the inverse-design of aircraft configurations against stability and control and handling qualities requirements:

  • CFD and empirical aerodynamic derivative prediction
  • Subsonic to supersonic Mach numbers
  • Hinge moment derivative estimation
  • Classical stability and control analysis
  • Tail and control surface sizing for trim, stick forces, nose wheel lift-off, VMCA etc.
  • Dynamic stability analysis using quasi steady and Eigenvalue methods: Dutch roll, spiral mode, short period
  • Assessment of applicable regulations including Part 23/25 and MIL-8785
  • Wind tunnel development for basic characteristics as well as high alpha and sideslip


Flight Dynamics Simulations:

  • Classical engineering design calculations
    • Longitudinal and lateral dynamics
    • Short period and Phugoid (stick fixed and free)
    • Dutch roll and spiral mode
  • Part 23/25 and MIL-8785 Handling Assessment
  • Stall maneuvers and deep stall recovery
  • Relationships with Part 23/25 Flight Analyst DERs
  • Trim runaway
  • Upset maneuver
  • Yaw over swing
  • Roll response
  • Tail strike
  • Takeoff Path
  • Elevator to Rotate
  • VMCa
