RT-LAB TestFlight

The model does not represent any aircraft in particular, it fits into the medium sized jet aircraft comparable to the regional jet category. It is realistic enough to simulate an aircraft flying in 6-dof, with proper flight dynamic modes and non-linear transonic aerodynamics.

• The aircraft dynamics is represented by a 6 DOF equations of motion model using quaternions to avoid singularities.
  
  
• The aerodynamics block provides the 6 dimensionalized forces and moments as outputs: Lift, drag, and side forces; rolling, pitching and yawing moments.
  
  
• This model contains a simple propulsion group model made of twin jet engines.
  
  
• An atmospheric data model provides outputs such as airspeeds, angle of attack and sideslip angle, air pressure, temperatures and altitude. International standard atmosphere (ISA) values for absolute temperature, pressure, density, and speed of sound with reference to geopotential altitude are used. A simple wind gust model can be turned on or off from the display. Horizontal wind is constant and vertical gusts are random. The speed and direction of the horizontal wind are inputs to the block.
  
  
• The autopilot uses course and distance between navigational track waypoints. The display holds up to 5 user-entered waypoints defined with a latitude, longitude, altitude and ground speed. These points are used as steer-to points and target designation points. After reaching the last waypoint, the autopilot controls the aircraft in a ccircle loiter mode.
  
  
• The controls consist of the following simple (no force or rate limiting), servo actuator models: elevator, rudder, ailerons, flaps and stabilizer.
  
  
• An inertial navigation system is modeled to output the aircraft's position, velocity, attitude and heading reference data; it simulates gyroscopes, accelerometers, air speed sensors, altitude sensors, and flow incidence sensors.
  
  
• An air data computer is also modelized and provides barometric altimeter plus dynamic and static pressure data outputs.
