Abstract

The invention relates to a helicopter, which is shaped like a toy plastic flying saucer, and directly drives propellers on the periphery of a cabin body to rotate by using a novel engine without shaft rotation or a speed reducing mechanism and a base so as to generate lift force to vertically take off and land and stop the helicopter in the air; the other engine generates thrust to make the airplane fly forward at high speed. The aircraft is very stable in vertical take-off and landing, staying in the air and flying; it has flexible steering; when the military aircraft is used as a military aircraft, weapons can be launched in different directions of forward, backward, leftward and rightward without changing the flight direction, and enemy targets can be struck; when the airplane is used as a civil airplane, the airplane can be used for shooting, scientific research or the like; and can also be used for civil aviation.

Description

a helicopter

The invention relates to an aircraft, in particular to an aircraft capable of vertical take-off and landing.

The current helicopter is generally powered by the engine, after the speed is changed, the shaft is turned to the propeller on the top to rotate to generate lift, and it takes off and lands vertically or stays in the air. This kind of helicopter, due to the long propeller, takes off and lands and stays in the air relatively stably, but the material index of the propeller is quite high, and the flight speed is relatively slow.

There is also a vertical take-off and landing that adopts the method of jet engine torsion nozzle downward jetting when taking off and landing. This kind of helicopter flies faster, but it takes off and lands and stays in the air for a short time, and it is not too stable.

The present invention will provide a kind of new helicopter, and it can effectively overcome the weakness of above two kinds of helicopters, reaches the purpose that takeoff and landing and staying in the air are relatively stable, and the speed when flying is faster again.

The purpose of the present invention is achieved like this:

The shape of the aircraft is round and oblate, with a large circular cabin in the middle for passengers and loads. A (new) engine (new working principle) is installed on the outer periphery of the cabin. Install two layers of propellers with opposite torsion angles and opposite rotations (the reaction forces generated by the upper and lower layers of propellers offset each other when rotating, so that the cabin will not rotate), and generate lift when synchronously rotating. Point the recoil force of the downward jet, can make the aircraft take off and land vertically or stay in the air. Load onto the horizontal thrust engine (jet type or turbine type all can) on the axis line perpendicular to cabin body, produce horizontal thrust and can make this aircraft fast horizontal flight. The thrust engine can rotate 360 degrees around the axis of the cabin to achieve the purpose of rapidly changing the flight direction. The overall structural center of gravity of the aircraft is below the propeller.

Concrete structure of the present invention is given in the following examples and accompanying drawings:

Concrete structure and working condition of the present invention are described in detail below in conjunction with accompanying drawing:

Helicopter profile of the present invention is round oblate spherical shape, as shown in accompanying drawing 1, is 1 arc arched hatch cover above, and the middle is a big circular cabin body, and is a kind of (new type) in the circular cabin outer periphery Engines (9, 2, 14, 6, 13), on the upper fuselage (2 engine cylinder blocks) of the engine, 3 upper deck propellers rotating clockwise are housed, on the lower fuselage (6 engine cylinder heads) of the engine There are 4 lower propellers that rotate counterclockwise, the teeth on the 2 cylinders and 6 cylinder heads are meshed with the 14 synchronous gears whose shafts are on the 9 body, the 3 upper propellers on the 2 cylinders rotate clockwise, and the 6 cylinders on the head The 4 lower propellers turn counterclockwise and are synchronized. Because the twist angle of the 3 upper deck propellers is opposite to that of the 4 lower deck propellers, the same lift is produced when concentrically and synchronously rotated in different directions, and the recoil force of the downward jet of the engine 5 exhaust port can make the aircraft take off and land vertically and stay in the air. Load onto level 7 thrust engines (jet type or turbine type all can) on the axis line perpendicular to cabin body, produce horizontal thrust and can make this machine fast horizontal flight. The 7-thrust engine can rotate 360 degrees around the axis of the cabin to achieve the purpose of changing direction. 8 hangers that can rotate 360 degrees can be loaded onto below the 7 thrust engines.

This novel engine comprises 9 bodies, 2 cylinder blocks that rotate clockwise and 6 cylinder heads that rotate counterclockwise and 14 synchronous gears and 13 engine mounting baffles that can make 2 cylinder blocks and 6 cylinder heads rotate in different directions.

The 9 body of the new engine is cylindrical, and the upper half of the wall of the 9 body (the part that is straight to the rotating 2 cylinder block) is provided with 10 air intake holes and 16 ignition devices. The 2 cylinder body of the new engine is circular Ring-shaped, set on the upper part of the body of the cylinder 9, the cylinder port of the 11 combustion chamber is aligned with the 10 air inlet of the 9 body and the 16 ignition device, the 11 combustion chamber is in the shape of a centrifugal parabola, and the gas outlet of the 11 combustion chamber is inclined downward , aligned with the 12-blade section on the 6-cylinder head. The 6-cylinder head of the new engine is also in the shape of a ring, which is set on the lower half of the cylindrical 9 body. There are 12 blades aligned with the gas outlet of the 2-cylinder body. The high-pressure gas after combustion is sprayed to the 12 blades to perform work. , and exhaust, there is a plane aligned with the gas outlet of the 11 combustion chambers to close the gas outlet when rotating. The 14 synchronous gears of the new engine are installed between the 2 cylinder block and the 6 cylinder head and the 9 body. On the 2-cylinder body and the 6-cylinder head, the synchronous gear meshing of the tooth and the shaft on the 9-body body is respectively arranged, so that the 2-cylinder body can be made to rotate clockwise, and the 6-cylinder head rotates counterclockwise, and are synchronized.

The working principle of the new engine is as follows: 2-cylinder and 6-cylinder heads rotate concentrically and synchronously in different directions;

1. Air intake: 10 air intake holes are opened, and the gas (compressed mixed gas) enters the 11 combustion chamber in the 2 cylinder body from the 10 air intake holes on the 9 body;

2. Close 10 air inlets;

3. Ignition: the 16 ignition device ignites the gas in the combustion chamber of the 2 cylinder block 11 to make it burn;

4. Exhaust open;

5. Work: high temperature and high pressure gas is sprayed to the 12 blades on the 6 cylinder head to do work;

6. Exhaust: The centrifugal force of the rotation of the 2-cylinder 11 combustion chamber centrifuges the exhaust gas in the 11 combustion chamber and the 12 blades on the 6-cylinder head rotate to generate negative pressure to suck out the exhaust gas in the 11 combustion chamber;

7. Close the cylinder exhaust port. Enter the next cycle.

This novel engine diameter is bigger, can have multiple 10 intake holes and have 11 combustion chambers, 12 blades on the 6 cylinder heads that are less than half of the number of 10 intake holes. There can also be multiple 14 synchronous gears.

When this novel helicopter is used as civilian, 3,4 screw propellers that are contained on engine 2 cylinder blocks and 6 cylinder heads can be slightly longer, also can only adorn one deck 3 screw propellers, load onto tail rudder on 1 cabin body. 8 suspensions that can rotate 360 degrees can be installed below the 7 thrust engines, which can be used for photography, scientific research or other. It can also be used as a civil aviation aircraft.

When this new type of aircraft is used as military, the 3 and 4 propellers installed on the 2-cylinder block and 6-cylinder head of the engine can be shorter, or the 3 and 4 propellers can not be adorned, and the recoil force of the direct downward jet of more than 5 exhaust ports on the circumference can be used. , just can make the aircraft take off and land vertically and stay in the air. On the disc below the 7 thrust engines, the 8 suspensions that can rotate 360 degrees can be weapon launchers, so that when the flight direction does not change, the enemy targets in all directions, front, rear, left, and right can be hit.

This aircraft also can drive 3,4 screw propellers at the cabin body circumference place with existing engine at present to produce lift, makes the vertical take-off and landing of the aircraft and stays in the air, is different from the helicopter that current propeller is contained on the top. Purpose is: under the same rotating speed situation of equal lift, be contained in the 3,4 helix lengths of cabin body circumference place can be shorter. It can also be said that when the length of the propellers is equal and the rotation speed is the same, the lift generated by the 3 and 4 propellers installed at the circumference of the nacelle when they rotate is much greater than that produced by the propellers mounted on the top of the machine. Because the 3 and 4 propellers of this machine are installed at the circumference of the cabin body, the diameter is equal to the diameter of the cabin body plus the diameter of the propeller when rotating, the lift area is larger, and the lift force point acts on the circumference of the cabin body evenly, and the rotating object is like a mound. Like a snail, it tries to stay level, so the aircraft is relatively stable when it takes off, lands, flies and stays in the air. Because the aircraft is equipped with one or several 7-thrust engines that produce horizontal thrust specially, the flight speed of the aircraft is relatively fast.

When the aircraft was flying at high speed, when the lift produced by the convex surface of the cabin was balanced with the earth's attraction to the aircraft, the aircraft could turn off the lift motors driving 3 and 4 propellers, and it could fly at a high speed by the 7 thrust motors. Because this nacelle cover is arc-arched, like the shell of a tortoise, it can be made of transparent plastic with low density and high strength; and the power directly acts on the 3 and 4 propellers, without a rotating shaft, without a reducer, without an engine frame, Therefore, the weight of the whole aircraft is relatively light, thereby achieving the purpose of simple structure, low manufacturing cost, and relatively fuel-efficient and economical flight. Because this fuselage is light and body is big (diameter is bigger), when a mechanical failure occurs in the air or an engine stops, it works by another engine, and this machine can also rotate and land slowly like a toy plastic frisbee. Or open the top cover of the machine to allow the driver and passengers to eject the cabin body to parachute and land, so the machine is safe and reliable.

Because the 2-cylinder block and 6-cylinder head of the machine engine and the 3 and 4 two-layer propellers rotate concentrically and synchronously out of phase, they perfectly utilize Newton's third law, so the design of the machine is more reasonable. Because the torsion angles of the 3 and 4 two-layer propellers are opposite, they generate lift at the same time; in addition, the combustion chamber of the machine rotates without transmission shafts, reducers, pistons, connecting rods, etc., so the mechanical efficiency of the machine is very high.
