Problems solved by technology

[0002] Disadvantages of modern helicopters: (1) During cruising, the rotor tilts forward to provide both lift and forward pulling force. Because the quality factor of the rotor is too low, the energy loss is too large, so the range of the helicopter is too short, which leads to Incapable of carrying out missions in deserts and grasslands, let alone flying across oceans

Abstract

This invention relates to a drive vertical aircraft technique field and especially to a device without rotary blades, which comprises motor, gearbox and fan and also left and right block plates of the semi-fan hole. The gas flow from the fan is located with blade group structure composed of blades, wherein each blade is located on the left and right block plate through its end axis and is distributed from high to low and the blade group is located with blade facing angel adjusting structure.

Description

Technical field: [0001] The invention relates to the technical field of active vertical lift-off aircraft, in particular to a rotorless vertical lift-off device. Background technique: [0002] Disadvantages of modern helicopters: (1) During cruising, the rotor tilts forward to provide both lift and forward pulling force. Because the quality factor of the rotor is too low, the energy loss is too large, so the range of the helicopter is too short, which leads to , the desert, and the grasslands are unable to perform tasks, let alone fly across the ocean. (2) The rotor is flying naked and violently, and cannot walk through complex ground features to perform rescue, fire fighting and arrest. Invention content: [0003] The purpose of the present invention is to provide a vertical lift and overcome the disadvantages (2) in the background technology, with a high C L : C D The dead wing provides the lift in cruising, overcomes the drawback (2) described in the background techn...
