FIELD: toys. SUBSTANCE: invention is related to toys which can contribute to performance of interesting competitions, to expand technical outlook in field of understanding of physical basis of flight of vehicles heavier that air and of some principles of operation of pneumatic devices. Invention expands range of possibilities of appearance of flying semi-copies with imitated prototypes of planes, provides for growth of their flight characteristics, increases entertainment of usage, ensures rise of effective usage of starting pulse with launching and touchdown safe for the surrounding people and enhances probability of detection of toy after its landing. Toy has thin forming shell imitating appearance of copied plane. Shell houses set of telescopic tubes which number is even or corresponds to number of engines of copied plane. Set of telescopic tubes is composed of immobile embracing tube with check valves, calibrated and adjustable holes for cross-over, mobile embraced tube with belts which is mounted for movement along axis of toy under action of starting pulse and returns back under action of spring, launching tube which has annular grooves in its outer surface coupled with the use of small diameter holes to its inner cavity. Outer surface of launching tube is covered with elastic polymer film with low friction coefficient. Launching tube has capability of sliding inside mobile tube right up to complete separation. Shell is closed in nose and tail parts of toy with immobile tubes. Gas-tight cavities filled with harmless gas are formed between them. Toy is equipped with sound-emitting unit which is switched on by starting pulse. Lifting surfaces of toy are fitted with ailerons with frictional registration of their angular position. EFFECT: expanded functional capabilities of flying toy. |
