FIELD: transport.
SUBSTANCE: proposed system comprises modular drone. Drone fuselage central frame is composed of detachable composite tube tightly fitted in cylindrical holder arranged in fuselage with its lengthwise axis perpendicular to fuselage lengthwise axis. Tube peripheral parts are tightly fitted in cylindrical holders arranged in wing left and right sections. Disc-like inserts made of composite material are arranged on tube ends fitted in lateral holders. One edge of lateral holders is jointed to first ribs of with left and right parts abutting the fuselage while second edge of said holders extending through second ribs of wing left and right parts is rigidly secured to first frames of wing left and right parts with respect to leading edge. Lock joints between wing left and right parts and fuselage comprises metal bolts, appropriate sleeves, two lateral holes in fuselage and two vertical bayonet spring.
EFFECT: higher strength and reliability, lower weight.
