Description
Technical field:
Title of the present utility model is:" the double mode rotary wing aircraft based on folding wing " belongs to aviation field.
Background technology:
Rotary wing aircraft (including helicopter and rotor VTOL aircraft), and Fixed-Wing is two kinds of different types
Airborne vehicle, so that helicopter and fixed wing aircraft compare as an example, helicopter is to produce downwash flow by main rotor rotation to go straight up to
Machine provides prevailing lift, and fixed wing aircraft is for aircraft to provide prevailing lift by wing, and the advantage and fixed-wing of helicopter are flown
The advantage of machine is combined, and is always the direction technically made great efforts, if but by lifting airscrew, and fixed wing aircraft wing simultaneously
Applied to an airplane, effect is conflicting between them, and prior art is difficult to solve this problem, and folding wing
Appearance there is provided solve problem method.
The content of the invention:
The purpose of this utility model is:By the folding wing (patent No.:201620324195;201610228024.1;Folding
The optimization patent No. of stacked wing:201610830956.3) rotary wing aircraft is applied to, so that by rotary wind type airborne vehicle and fixation
Wing airborne vehicle is combined, and constitutes double mode rotary wing aircraft, the advantage for making it be provided simultaneously with two kinds of airborne vehicles.
Feature of the present utility model is:By technical measures, folding wing is applied to rotary wing aircraft, bimodulus is constituted
Formula rotary wing aircraft, i.e.,;Rotary wing aircraft is taken off, landing phases, and lift is provided by rotor wing rotation, and implementation is taken off vertically, landed
Pattern, in the rotary wing aircraft flat winged stage, implements fixed wing aircraft offline mode.
Further:By taking helicopter as an example, folding wing is applied to helicopter, double mode helicopter is constituted, folded
Formula wing is arranged on helicopter fuselage bottom, takes off, landing phases, and wing-folding is drawn in below fuselage, by engine driving
Main rotor rotation provides lift, by the Mode normal landing of helicopter;
Further:Unfolded formula wing when double mode helicopter is flat winged in the air, formation can produce the fixation machine of lift
The wing, thrust (pulling force) propeller provides flying power, prevailing lift is provided by wing, by the mode flight of fixed wing aircraft;
