Embodiment Construction

[0014] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments, but not as a basis for any limitation of the present invention.

[0015] Example. like figure 1 The generator of the present invention shown is installed horizontally, figure 1 The arrows in indicate the flight direction of the aircraft. The method of installing the generator on the UAV, the generator is a JF3.5kW / 28V DC generator, the input shaft of the generator is a spline shaft, and the radial runout of the spline shaft is not more than 0.2mm; the input shaft of the generator is The coupling is directly and rigidly connected with the flywheel disc at the output end of the engine to ensure rapid and accurate transmission of the engine output torque and minimize power loss during transmission. The coupling is provided with a spline hole connected with the generator and several connection holes connected with the flywheel disc at the output ...

Abstract

The invention discloses a method and a structure for installing an electricity generator on an unmanned plane. The electricity generator is a JF 3.5kw / 28V direct-current electricity generator, wherein the input shaft of the electricity generator is a spline shaft; the radial runout of the spline shaft is not more than 0.2mm; and the input shaft of the electricity generator is rigidly connected with a flying wheel plate of an output shaft of an engine directly through a coupler, so that the output torque of the engine is ensured to be quickly and accurately transmitted and the power loss is minimal in a transmission process. By the method and the structure, the installation is reliable, the running is stable, overmuch engine output power is not used, the power demand of pickaback and task equipment of the unmanned plane can be ensured when the unmanned plane flies, the engine output power consumed by the electricity generator is ensured to be minimal when power equipment normally runs, and the working efficiency of the 3.5kw / 28V direct-current electricity generator is improved.

Description

technical field [0001] The invention relates to a method and structure for installing a generator on an unmanned aerial vehicle, and belongs to the technical field of unmanned aerial vehicle transmission connection. Background technique [0002] At present, the airborne and mission equipment used by unmanned aircraft in China are all 28V high-power electrical equipment. Since the power supply equipment provided by the piston engine is a maximum of 800W / 12V DC engine, it can no longer meet the needs of airborne and mission equipment. In view of the special requirements for power supply equipment in the development of unmanned aircraft, a new installation design for the domestically produced 3.5kW / 28V DC generator is required to maximize the capacity of power supply equipment on unmanned aircraft in a stable, safe and reliable manner. special requirements. However, the current technology of installing generators on drones cannot meet this special requirement. Contents of t...
