The K-37 rocket-parachute system (RPS) is designed for pilot's ejection from a helicopter in emergency using a towing rocket motor, which pulls the pilot out of the cockpit. The seat stays in the helicopter.
Usage of the pulling motor provides automatically for system stabilization during a propulsion phase, and escape from the helicopter through a small-sized hatch. A modularity principle used in this system makes it possible to apply the RPS in various aircraft. The system makes it possible to bailout with a parachute system.
The K-37 seat ensures escape within the range of V_e=0-400 km/h and H=0-4000 m (including V=0 and H=0). It has a stepless height adjustment range of 170 mm. The installation weight of the fully equipped seat does not exceed 94 kg (including the parachute system, survival kit and Combined Service Connector).
