Hybrid power airship adopting inflated wings and cycloidal propellers

Abstract

The invention provides a hybrid power airship adopting inflated wings and cycloidal propellers. The hybrid power airship comprises an airship body, a thin film solar cell array and an oxygen-hydrogen fuel battery pack, cycloidal propeller thrusters, inflated wings, a V-shaped empennage, undercarriages, a load cabin and a control system, wherein the thin film solar cell array is covered on the upper surface of the airship body, the plurality of cycloidal propeller thrusters are symmetrically arranged at two sides of the airship body along a longitudinal symmetric surface of the airship body, a drive device of the cycloidal propeller thrusters is positioned in the airship body, the V-shaped empennage is fixed at the tail part of the airship body, the undercarriages are arranged at the bottom of the airship by adopting a front-three-point manner, the inflated wings are positioned at the left side and the right side of the airship body, and the load cabin and the oxygen-hydrogen fuel battery pack are positioned at the belly part of the airship body. According to the hybrid power airship, the cycloidal propellers, the airship and the inflated wings are combined so that helium bags with high cost do not need to be installed in the airship body, the volume of the airship is reduced, and the weight and cost are saved; by using the cycloidal propellers as propelling devices of the airship and forming a compound control system together with the V-shaped empennage, the control responding speed of the airship is increased.

Description

technical field [0001] The invention belongs to the technical field of aviation aircraft, in particular to a hybrid power airship adopting inflatable wings and cycloidal propellers. Background technique [0002] Entering the 21st century, the development of aviation technology and concepts is changing with each passing day. As a platform for transportation, reconnaissance, relay, and early warning, airships will play an important role in the future military and civilian sectors. [0003] People such as Liu Chunqiao disclosed a kind of lifting airship in the Chinese patent that the patent No. is CN1378949A, and this airship uses the compression system to compress the light gas in the outer layer airbag of the airship to the inner layer air storage cyst or to compress the high pressure in the inner layer air storage bag. The light gas (or high-pressure liquid) is released to the outer layer, and the air (or liquid) pressure outside the airbag changes the volume of the air (or ...

AI Technical Summary

Problems solved by technology

The disadvantage of this airship scheme is that the propeller tilting mechanism is complex and difficult to operate, which reduces its reliability; in addition, the propeller is installed on the upper surface of the hull, and the axis of the propeller is perpendicular to the ground during vertical takeoff, landing and hovering. , at this time the propeller slipstream directly flows through the upper surface of the hull, which is not conducive to generating lift, and brings strong propeller-body interference, which reduces flight stability

[0005] On the whole, the traditional airship has the following disadvantages: the principle of lift-off is mainly to fill the interior of the airship with a gas lighter than air to form buoyancy. The total weight of the airship will make the airship huge, not only costly, but also difficult to manufacture

In addition, with the consumption of fuel, the weight of the airship will decrease, and it is necessary to adjust the weight of the airship through ballast operation, so as to achieve the static balance of the airship, and the ballast and its auxiliary recovery system will increase the weight of the airship and reduce the load of the airship; The airship propeller of the rotary propulsion system has a limited tilting angle, the tilting mechanism is complicated, and the reliability is low
