摘要

FIELD: transport.;SUBSTANCE: invention relates to parachuter training. proposed device comprises flight chamber to allow parachuter to experience free fall sensation. Air flow supporting parachuter is generated by blowers communicated above flight chamber via channel. Intermediate platform with opening into flight chamber adjoins the latter. One or two air return channels are used to force air from blower outlet to blower inlet. One segment of said channel comprises opposed shutters to control temperature by forced feed of ambient air into imitator. Several said channels with diverging walls may be used.;EFFECT: decreased height, higher commercial value.;46 cl, 35 dwg
