Abstract
The utility model relates to a teaching exercise tool. Nozzles of water-gas booster-type pressure cavities of the water-gas booster-type teaching flight device are provided with conical nozzles. The utility model has the advantages of simple structure, farther flying distance, and safe landing.
Description
The utility model belongs to the education exercising tool, particularly relates to a kind of water---gas booster-type teaching aircraft.
The teaching aircraft that the application is related, usually form by aircraft body and guiding empennage and launcher, the rear portion of aircraft body is the charge pressure storehouse of water filling, by external pressure air is compressed in water ballast is pressed, bottom, pressure storehouse is a jet pipe, be locked in before the emission in the control socket that has quick release mechanism and fix with launcher, this socket can flexibly connect with aerating device, and the pneumatic type retaining valve wherein is housed.Teaching with the flight of aircraft and jet airplane and delivery fire preceding the same all be to utilize the recoil strength of the course of injection generation of certain material to advance, the former is the water that pressure-air drives, the latter then is combustion gas, and this teaching aircraft is that the rudimentary knowledge that the teenager understands about flight has played positive effect.Yet this teaching exists the short obvious deficiency of flying distance with aircraft.
The purpose of this utility model is to a kind of improvement of above-mentioned teaching with aircraft, provides a kind of flying distance water far away---gas booster-type teaching aircraft.
Above-mentioned purpose is achieved through the following technical solutions: the jet pipe 7 in pressure storehouse 3 is provided with conical nozzle 9.
The termination 5 of aircraft body 4 is a light elastomerics.
Below with drawings and Examples explanation the utility model.
Accompanying drawing 1 embodiment profile synoptic diagram
Accompanying drawing 2 nozzle structure synoptic diagram
Among the figure: 1 guiding empennage, 2 launchers, 3 pressure storehouses, 4 aircraft body, 5 terminations, 6 water, 7 jet pipes, 8 control sockets, 9 conical nozzles.
Embodiment illustrated in fig. 1 is the simulated rocket that can launch, jet pipe 7 structures that wherein are threaded with pressure storehouse 3 as shown in Figure 2, as seen jet pipe is provided with conical nozzle 9, its tapering is neglected pressure storehouse 3 volumes greatly and is decided, the bigger then tapering of conical nozzle in pressure storehouse should suitably increase, learn by test, the complete surely identical teaching of two structures and size is with before simulating fire, under the identical situation of water filling of pressure storehouse and air pressure, adopt conical nozzle to be significantly increased than its flying distance of simulated rocket of straight hole spout, this is because quality and speed that conical nozzle sprayed are higher than the straight hole spout, the recoil thrust that rocket is obtained according to law of conservation of momentum conical nozzle must increase, so flying distance will obviously increase.Identical two mathematics rockets of structure and size for example, its pressure storage capacity is all 1mL mutually, all injects 3/5ths water, and is filled with 2Kgf/cm equally
2Air pressure, the launcher elevation angle is all 60 °, the teaching that the result has a conical nozzle is with 200 meters of rocket flights, and the teaching of straight hole spout is only flown 117 meters with rocket.
Light elastomerics are adopted in its termination of aircraft body of the present utility model 5 is that microcellular foam is made, and not only having alleviated teaching and having helped the raising of flying distance with the oeverall quality of aircraft, and the while also can be cushioned aircraft and land impulse force, has increased security.
The utlity model has simple in structure, flying distance far away and land safe significantly Advantage.
Claims (2)
1, water---gas booster-type teaching aircraft by aircraft body and lead empennage, launcher, jet pipe and have snap-out release emission control socket and formed, is characterized in that: water---the jet pipe in gas booster-type pressure storehouse is provided with conical nozzle.
2, teaching aircraft as claimed in claim 1 is characterized in that: the termination of aircraft body is a light elastomerics.
