Abstract

An undercarriage (40) which combines both tracks (9) and tyres (14) is provided. During the landing roll phase, only the tracks (9) take the brunt of the impact, and the flaps (42, 42a) incorporated at a convenient spot near the mouth of the undercarriage well (12) are lowered to increase the drag for the aircraft. During the take-off phase, the flaps (42, 42a) are retracted, and the aircraft initially run on tracks (9) till it attains an optimum speed of the undercarriage (40) with tracks (9), once a sustainable lift is created the tyres (14) are then deployed to take off.
