Deformable airplane with front-rear double propeller and front-rear double wing

Abstract

The invention discloses a deformable airplane with a front-rear double propeller and a front-rear double wing. A front wing (1) and a rear wing (1) form the front-rear double wing. The structure is compact, stiffness and strength are good, enough lift force is provided by a large wing face, two rudders (3) and four horizontal rudders (4) provide good controllability, and the airplane is suitable for low-speed large-load cruising. The front-back double wing can deform, the front wing (1) can rotate, the rear wing (2) can be folded, the wingspan of the whole plane is adjustable to adapt to cruising at different speeds, and running on the ground, traction, transport and storage are also facilitated. The head and the tail of the airplane are each provided with a propeller (5), and the propellers are combined into a pair of reversing propellers to generate push force and pull force in the same direction. A power shaft is in the center and coincides with the propellers to offset torque, the weight of the whole airplane is moderate, the rolling inertia is small, rolling maneuverability is facilitated, and no wing face airflow interference exists. An airplane body upper shell and four wing upper shell structures are obtained through the photovoltaic assembly skin and honeycomb composite material lamination technology, the two wings and wing bodies are fused to provide large lighting area, the photovoltaic effect is facilitated, a secondary battery is charged in time, power is supplied to a system, long flight endurance is facilitated, and the airplane is environmentally friendly and safe.

Description

technical field [0001] The invention relates to a deformable aircraft with front and rear double propellers and double wings. Two wings and two vertical tails are beneficial for low-speed and heavy-load cruising; deformable wings are beneficial for variable-speed cruising and maintenance; front and rear reverse propeller drives avoid wing root stress concentration and airflow interference; photovoltaic and honeycomb composite lamination technology realizes lightweight structure and real-time Charging belongs to the field of overall aircraft design. Background technique [0002] Flying freely has been a dream pursued by human beings since ancient times. The Wright brothers pursued the dream of flying and invented the first airplane. However, shortly after World War I and World War II, airplanes ignored human beings because of their technical difficulty and overemphasis on their military use. The first wish - to fly freely. Although civil aviation developed vigorously based ...

Problems solved by technology

[0009] (2) Traditional monoplane or biplane aircraft are not easily deformed, and the lateral dimensions of the wingspan and rolling inertia remain unchanged. Forced variable speed cruise will easily lead to a significant drop in aerodynamic efficiency, and due to the large wingspan, it is not conducive to storage and handling. The wings can be deformed to solve the problem. these questions
