Embodiment Construction

[0039] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0040] A kind of flight stretcher of the present invention as shown in the accompanying drawing, it comprises support 14, and support 14 can adopt shapes such as circle, ellipse or square, it also comprises at least two main lift ducted fans and two inclination adjustments Ducted fans, at least two main lift ducted fans are installed symmetrically around the center of gravity of the bracket to prevent pitching and rolling. Optimum method: the main lift duct fan is installed symmetrically at the four corners of the two diagonals passing through the center of gravity of the bracket, as shown in the figure, respectively the main lift duct fan I1, the main lift duct fan II2, and the main lift duct Fan III3 and main lift duct fan IV4 are used to provide lift and control the pitching and rolling motion of the flying stretcher. The two tilt-adjusti...

Abstract

The invention discloses a flight stretcher, which includes a bracket, and it also includes two tilting adjustable ducted fans and at least two main lift ducted fans, at least two main lift ducted fans are symmetrically installed around the center of gravity of the bracket, Two tilt-adjustable ducted fans are symmetrically installed on the left and right sides of the center of gravity of the support along the flight direction, a plurality of supporting casters are installed on the support, and a man-carrying device is fixed on the top surface of the support. Multiple sets of fixing buckles for fixing the wounded. A bottom compartment is fixed on the bottom surface of the bracket, and a flight control module is installed in the bottom compartment. Some signal output components are directly connected to the flight control module, and the other part of the signal output components are processed through signal processing. The module is connected to the flight control module. The invention can not only take off and land vertically and hover like an unmanned helicopter, but also can quickly fly forward like a fixed-wing unmanned aerial vehicle, the flight control is simple and reliable, and the application prospect is broad.

Description

technical field [0001] The invention relates to an aircraft, in particular to a low-altitude, low-speed, short-distance multi-duct coaxial dual-rotor aircraft used for the evacuation of the wounded in disaster relief. Background technique [0002] The whole world suffers from a large number of natural disasters and man-made disasters every year, causing large-scale building collapse and casualties. Searching and rescuing survivors has become the most urgent task in disaster search and rescue work. However, the complexity, danger and urgency of search and rescue work at disaster sites have brought huge security threats to rescuers and survivors, as well as great difficulties and challenges to rescue work. [0003] At present, the rescue and evacuation of the wounded at the scene of large-scale disasters is mainly carried out on stretchers, supplemented by rescue vehicles and helicopters. However, traffic jams in the disaster area, complex terrain, scattered deployment of pe...
