FIELD: aircraft engineering.SUBSTANCE: hypersonic aircraft comprises fuselage, outer wings, multi-engine drive, two turbojets. Outer wings comprises root, mid and end sections furnished with hook at the end coaxially articulated in fuselage. Multi-engine drive is designed to vary wing span by simultaneous action at outer wing end sections both by lever of mechanism connected via screw gearing with motor shaft in lengthwise mirror plane and by moment of force from the shaft of appropriate lateral motor via planetary gearbox. Turbojet allows gas tapping to gas-dynamic system of control over pitch, bank and hunting.EFFECT: decreased drag at supersonic speed, higher controllability.6 cl, 18 dwg |
