Glider cantilever auxiliary motorised propulsion arrangement

摘要

The cantilever (1) upon which the airscrew is mounted is constructed similar to a fin and with a low resistance profile. A mechanical rotation transmission in the form of an internally revolving chain or toothed belt (16) is provided between the motor (6) in the fuselage (10) and the tear-shaped encased (12) airscrew shaft (5) which has rearwards folding blades. The cooling air feed of the motor is through extendable air scoops (11) in the direct proximity of the cantilever, or through separate covered openings at other points of the fuselage.
