We investigated an opportunity of air cushion chassis and light transport aircraft coordi-
nating. The key layout solution was the complete rising of the air-cushion undercarriage
in specialized gondolas after take-off. It is shown, that the integration of air cushion
chassis platform into the glider demands expansion of empennage area. To parry desta-
bilize moments from air cushion platform with open front and rear shields the blow of
empennage with airscrew jets is to be organized. To maintain controllability during take-
off and landing appropriate measures should be taken. The simplest way to increase con-
trollability is differential control of engines traction or mounting of extra fins in airscrew
jets flow area. The most rational layout decision is the front placement of air-cushion
supercharger. It is shown, that the procedure of coordinating base layout of airplane
with air-cushion chassis should be carried out at the draft stage.
Key words:
layout, aircraft, undercarriage, air-cushion, integration.
