Dynamic simulation software

2. Helicopter engine dynamics simulation.
– Simulate engine dynamics during the main processes:
+ Engine start-up process;
+ Engine operation during successful start-up, normal operation of both engines, individual engine testing, intentional engine shutdown;
+ Engine shutdown process.
– Input signals in engine dynamics simulation:
+ Throttle position;
+ Collective lever position;
+ Engine shut-off lever position;
+ Individual control lever position;
+ Engine start switch position (“right” – “left”);
+ Start button signal.
– Output parameters of engine dynamics simulation:
+ Turbine compressor rotor speed of each engine;
+ Main rotor speed;
+ T3 turbine inlet temperature;
+ Temperature and pressure of each engine’s lubricant oil.
– Calculation cycle: ≤ 0.05 s.

3. Flight mode simulation.
Simulate the following scenarios:
+ Pre-start cockpit and systems check;
+ Start-up, pre-takeoff systems check;
+ Taxiing on hard, flat surface;
+ Takeoff modes: Vertical takeoff; Rolling takeoff; Combined takeoff;
+ Climb;
+ Level flight;
+ Flight mode transitions: From climb to hover; From hover to descent; From hover to level flight and vice versa; From level flight to autorotation and vice versa;
+ Straight descent with engines operating;
+ Descending flight with engines operating;
+ Instrument flight;
+ Long-range flight;
+ Long-range flight with field change;
+ Cloud penetration flight;
+ No-ground-reference flight;
+ Flight using onboard systems;
+ Flight handling in-flight emergencies;
+ Landing.
– Processing cycle: ≤ 0.05 s.
