Problems solved by technology

The "flying car" that combines an airplane and a car is not practical because it cannot be helicoptered and needs frequent and troublesome disassembly
In recent years, the "flying cars" developed by some foreign experts, such as the M400 of the American Muller International Company, etc., have complex structures, expensive costs, and are far from the structure of automobiles. They are difficult to adapt to long-distance road driving, are not generally available, and are reliable and safe. Suspicious
In addition, the method of changing the engine speed by changing the throttle to change the speed and lift of the lift fan is not safe due to the lag of the fan response

Embodiment Construction

[0004] The purpose of the present invention can be achieved through the following technical solutions:

[0005] On the air inlet of the reciprocally reversible double-rotor ducted lift fan cylinder 5, (connected through the bendable compensation joint 12) is installed a relatively rotatable double layer (made of light metal, alloy or composite material with equally spaced louvers) The air intake volume (air flow) control valve 1 (Fig. 8) formed by a hemispherical shell (or semi-ellipsoidal shell) is directly regulated by the opening and closing of the actuating mechanism 23 by relatively rotating the hemispherical shell (semi-ellipsoidal shell) and adjusting the ventilation area of ​​the louver. Air volume (linkage regulation engine throttle) controls the lift that fan rotor 6 (Fig. 13) produces. There is an emergency parachute storehouse 2 in the center of the top of the shell, and the parachute is folded and stored, and can be compressed air (or the explosive method of burni...

Abstract

A method for controlling the lift force of the rotary wings features that an airflow valve with a rotationally opened or closed and perforated dual-layer semi-spherical (or semi-elliptical) casing is used to control the air flow in channel, so controlling the lift force. A helicopter-type car based on said method is composed of dual-layer rotary wings and their air channel, bottom jet nozzle group and its airflow regulating grate group, the foldable and telescopic auxiliary wings at both sides, two vertical tail wings (and direction helm), two horizontal tail wings (and lift helm), tail nozzle, engine, driver cab, and manipulating mechanism.

Description

technical field [0001] The invention relates to a new lift control method of a rotor fan, a ducted rotor lift fan using the method and a practical helicopter (sedan car) that can be lifted up, belonging to new (household, public) land, air (and water surface) transportation ( tour) tool technology field. Background technique [0002] Existing helicopters adopt a variable pitch mechanism to change the angle of attack of the rotor blades and then change the rotor pitch to control the lift, which makes the structure of the rotor hub complex, the overall structural strength and reliability of the rotor are not high, and it is not suitable for high-speed rotation (generally about 200 revolutions per minute) ), and only adopt large-diameter rotor in order to obtain large lift (existing manned helicopter rotor diameter minimum also more than 5 meters), this determines general helicopter (and the " helicopter flying car that helicopter rotor and automobile are assembled and combined...
