The invention provides a multifunctional lightweight unmanned helicopter. The multifunctional lightweight unmanned helicopter is characterized in that a helicopter body is a three-dimensional space truss formed by welding long tubes; the inner part of the helicopter body is divided into an upper onboard layer and a lower onboard layer which are separated through a conductive metal separating plate; an oil tank is arranged in the helicopter body; a head of the helicopter body is in a shape of a rectangular pyramid; long tubes correspondingly backwards extend from four top points on the bottom surface of the head to form a polygonal side surfaces with two symmetric sides; cross beams which are arranged in parallel in the front and back of an undercarriage fixedly sleeve the bottom part of the head; connecting clamping sheets are correspondingly vertically arranged on the top parts of the side surfaces of the two sides of the head, and a speed reducer is fixed between the connecting clamping sheets; the rear part of the speed reducer is connected to one end of a horizontally-arranged long barrel-shaped tail tube; a turbine engine is arranged at the lower part of the speed reducer; a tail rotor and an empennage are arranged at one end of the speed reducer; a flow guide heat-dissipating shied is fixed in the front of the speed reducer. The whole layout of the multifunctional lightweight unmanned helicopter is redesigned to solve the problem of extremely high fault rate caused by design defect of the existing unmanned helicopter.
