COMPARISON OF POWERED-LIFT TURBOFAN AIRCRAFT WITH CONVENTIONAL TURBOPROP AIRCRAFT FOR ESTOL APPLICATION

摘要

The focus of this paper is on methods for field performance calculation of powered-lift internally blown flaps (IBF) turbofan aircraft and conventional turboprop aircraft. These methods are the basis for the sizing of extreme short takeoff and landing (ESTOL) aircraft, and, hence, the basis for a comparison the overall mission performance. In an application example, turbofan aircraft with IBF and conventional turboprop aircraft are sized for field length requirements between 600 m and 1000 m. Their mission performance is compared to a conventional takeoff and landing turbofan aircraft for a typical regional aircraft design mission.
