Embodiment 1

[0063] Flywheel catapult for military carrier aircraft

[0064] 1. The working process of the shipboard flywheel catapult

[0065] in the attached figure 1 , 2 , 3, 4, and 9:

[0066] When the aircraft (28) was in place, the wheels of the front landing gear (29) drove into the wheel grooves at the place, so that the fuselage was lowered, so that the guide wheels (35) were just in place on the ejection guide rail (36), Aircraft moves forward again, allows airborne rack (32) to mesh with drive gear (21), retracts nose landing gear then, allows the weight that nose landing gear bears to be pressed on guide wheel (35) fully.

[0067] 2. After the aircraft is successfully ignited, start the booster motor (15), mainly using the energy provided by the booster motor, plus the thrust of the aircraft engine and the friction of the differential coupling (3), the three forces work together to push the aircraft to start .

[0068] 3. When the rotational speed of the driving wheel (5) ...

[0295] Land Airport Flywheel Catapult

[0296] 1. Working process of land airport catapult

[0297] in the attached Figure 5 , 6 middle:

[0298] 1. The land airport has a relatively generous location and can provide a long-distance brake slideway (56). It is proposed to use the winches (51, 52)-steel cables (53) as the power to pull the traction shuttle (54), The transmission mechanism can be simplified and the weight can be reduced.

[0299] 2. Land airport catapults are suitable for ejecting military aircraft and civil aviation aircraft, and the take-off runway and landing runway should be set separately.

[0300] 3. Ordinary airports are equipped with single-power small and medium-sized catapults, which can eject aircrafts below 90 tons. Large-scale airports are equipped with dual-power large-scale catapults, equipped with 1 to 2 sets of medium-sized winches and 1 set of large winches, which can eject two aircrafts below 90 tons at the same time; the combination of t...

[0435] Operation Rocket Flywheel Catapult

[0436] 1. The working process of the rocket catapult

[0437] in the attached Figure 7 middle:

[0438] 1. The rocket catapult is equipped with 4 sets of power systems (2, 68, 69, 70). It is planned to activate the number of power systems according to the thrust requirements.

[0439] 2. Set the final rotational speed of the flywheel (2) according to the required final ejection velocity.

[0440] 3. According to the diameter of the rocket (67), adjust the length of the telescopic branch transmission shaft (74) of the launching frame, so that the drive gear (21) and the hedge drive gear (76) are meshed with the rocket rack (73). Let the guide slide rod (77) embed in the guide chute (78).

[0441] 4. The rocket (67) is in place, and the launcher receives a take-off command, and after the rocket is successfully ignited, the ejection system is started.

[0442] 5. The rocket rack (73) arrives at the set position, the travel switch ...

Abstract

The invention provides a flywheel catapult. The flywheel catapult converts energy stored by a flywheel into a linear thrust force so that an ejected object obtains an extremely high speed within a short time; and the main parts and the part acting sequence of the flywheel catapult are the flywheel, a differential shaft coupling, a transmission, a drive mechanism, driving gears, a driven rack and an aircraft. The core technology is a conical spiral rack stepless transmission; and the flywheel drives the transmission to output stepless accelerated rotation. The core technology II is interlinked drive; the plurality of driving gears are connected with one main shaft in series; and these driving gears drive the driven rack in sequence to finally obtain accelerated linear motion. A carrier-based aircraft catapult listed in the invention has the characteristics that the weight is 100 tons, the volume is 100 m3, the source power is 5000 kw, the diameter of the flywheel is 4m, the weight of the flywheel is 26 tons, the average load of an assisted motor is 10000 kw, the power torque is more than 500 kN.m, the traditional catapult-assisted take-off weight is 45 tons, the average acceleration is 3.5 g, the end speed is 70.65 m / s, the catapulting distance is 76.3 m, the power consumption of every catapulting is 50 kilowatt hours and the shortest circulation period is 30 seconds. The flywheel catapult is mainly used for catapulting military airplanes, civil airplanes, rockets, railway trains and so on.

Description

[0001] Technical field [0002] The invention relates to a flywheel catapult, which is a linear accelerator capable of releasing a large amount of energy in a very short time to accelerate a large-mass object to a very high speed. Flywheel catapults are mainly used to help aircraft take off, rocket launch, missile launch, shell launch, object throwing, rail train acceleration, car acceleration, elevator operation, cable car operation, etc. Background technique [0003] At present, catapults are mainly used in the military. The relatively mature catapult is the steam catapult. The sealing of the slit cylinder is the core technology. This technology requires that the traction shuttle can move freely at the slit of the cylinder, and it can be sealed in time. High temperature and high pressure steam in the cylinder. The disadvantages of steam catapults are many, mainly including the large difference in acceleration before and after the ejection, the preparation time is too long, ...
