Abstract The pilot project of new light civil turboprop aircraft, called the KhAI-90, featuring a cruising speed 350km/h, payload 600 kg at 500 km range, and equipped with two Rolls-Royce 250-B17F engines each power 420 hp (alternatively, AI-450C 450 may be installed) is presented herein. Based on developed technical task, concept for creating KhAI-90 competitive analysis prototypes’ aircraft p...

The purpose of an aircraft Takeoff Performance Monitoring System (TOPMS) is to provide to the pilot information pertaining to the level of safety with which a takeoff is proceeding. The authors have developed a theoretical dynamic model to investigate the feasibility of using an observer system during the roll and takeoff phases of aircraft operation to provide to the pilot the information that...
