MULTI-PURPOSE HEAVIER-THAN-AIR FLYING VEHICLE Russian patent published in 2004 - IPC

FIELD: manufacture of flying vehicles used as aircraft, helicopter or glider.

SUBSTANCE: proposed flying vehicle has fuselage with slotted aperture in upper portion under which strut is located used in "glider" mode. Said strut includes L-shaped unequal-arm lever and auxiliary lever articulated with singing axle of said unequal-arm lever. Drive motor is mounted on free ends of levers with propeller having folding blades. Smaller arm of unequal-arm lever is secured on shaft of toothed sector of strut turning mechanism. Worm of said sector is linked with drive for reciprocating motion of control carriage which is provided with lock of its front, intermediate and rear positions corresponding to "aircraft", "helicopter" and "glider" modes. Proposed flying vehicle has landing gear, lifting swept-forward wing and tail unit. Sweep forward angle “α” and angle “δ” between smaller and larger arms of unequal-arm lever are equal to 145-175 deg. and 90-100 deg., respectively. Length "T" of larger arm of this lever and length "L" of fuselage is lesser than diameter "D" of propeller and length "M" of wing by 1.65-2.1 and 2.55-2.85 times, respectively; length “T₁” of smaller arm of lever and distance "F" between nose section of fuselage and center section of fuselage is lesser than length "T" of larger arm of lever and length "L" of fuselage by 3.0-3.7 and 2.0-2.5 times, respectively.

EFFECT: improved service characteristics; low cost of manufacture.
