FIELD: engines and pumps. ^ SUBSTANCE: invention is related to rocket engineering and may be used in development of rocket engine dual-expander nozzles. Rocket engine dual-expander nozzle comprises fixed and sliding nozzles, and also two-element lever mechanisms for their alignment. When nozzles are in folded condition, two-element lever mechanisms are installed on the internal side of sliding nozzles. Points of lever mechanism elements to the nozzle, relative to which the following nozzle is displaced, are located at the half of its length. Total length of every lever mechanism elements makes half of nozzle traveling way. ^ EFFECT: reduction of rocket length by reduction of clearance between engine bottom and nozzle ends, and also reduction of length and weight of lever mechanism elements. ^ 2 dwg |
