The utility model has the advantages of simple structure and good simulation performance, and is an ideal sports apparatus.

Description

Model rocket

The utility model belongs to sports movement apparatus, is specifically related to a kind of flight and also can reclaims reusable model rocket.

So-called model rocket is meant a kind ofly have and the similar microrocket of large rocket, resemble to have emission, flight and recovery function the kidney-yang arrow.The model of sports at present has car mould, model plane, Hai Mo etc., and model rocket is a kind of model with space flight characteristic.Owing to be sports, exist very strong athletics, use the engine of international standard to carry out height, hang time during match and resemble the match of eight projects of true three major types, the ability to work of engine is the same, its games results are just got exhausted in the quality of rocket body performance, so the general shape of model rocket, internal structure, manufacture craft just become the key areas of sports.There is following problem in present model rocket: 1. rocket body adopts the stacked paper tube that rolls, and quality branch is inhomogeneous, is difficult to accomplish to maximizing, resembling trueization direction and develop; 2. the mode of its stationary engine is a friction-type, rely on the frictional force transferring power between motor body and the cylindrical shell, usually in flight course, the abnormality that engine is rushed in rocket body or the engine recoil is withdrawed from the parachute-opening process occurs, make abortive launch, cause rocket body to damage; 3. bonding empennage is manual finishing, and its human factor is very big, and empennage bonding location, angle are incorrect, make the rocket flight track irregular, can't reclaim control, cause unnecessary flying height loss.

The purpose of this utility model provide a kind of simple in structure, easy to operate, can stabilized flight, safe recovery, repeated use, model rocket that production technology is good.

This model rocket, form by arrow 1, parachute 2, rocket body 3, sleeve pipe 4, adaptive circle 5, grab 6, whole empennage 7, engine 8, an end that it is characterized in that rocket body 3 and arrow 1 close for inserting and connect, whole empennage 5 closes with the other end inserting of rocket body 3 and connects, U type grab 6 one ends insert by the top of sleeve pipe 4, the other end is stuck in the bottom of sleeve pipe 4, adaptive circle 5 combines as a whole rocket body 3 and sleeve pipe 4, the connection cord of parachute 2 combines as a whole by the link and the rocket body 3 of arrow 1 bottom, and engine 8 is contained in the sleeve pipe 4.

The another rocket body 3 that is characterized as of this utility model is the cylindrical body that is rolled into by the paper tape spiral roll extrusion through the glue dipping.

It is integral molded plastic moulding that another of this utility model is characterized as model rocket empennage 7.

This utility model has the following advantages:

1. have and resemble true property, weight is little, and the intensity height has reached International Aeronautical Federation's specified standard;

2. rocket body appearance looks elegant adopts the paper tape spiral roll extrusion of impregnation to roll and forms, and quality branch is even, can produce in enormous quantities;

3. engine is installed in the sleeve pipe of band grab, adaptive circle has connected rocket body and sleeve pipe with bonding form, the parachute-opening combustion gas is not leaked, engine is just blocked at the grab two ends, is convenient to the engine loading and unloading, guarantees that parachute-opening thrust reasonably is delivered to arrow from the grab front end, arrow, rocket body are separated, restraining force of engine is also given in the grab rear end, can not cause the engine recoil to be withdrawed from when parachute-opening, thereby protect the parachute-opening work of having put in order parachute reliably.

4. empennage adopts the moulding of engineering plastics integral molded plastic, the accuracy height, and flight stability is good.

5. rocket body, sleeve pipe, adaptive circle all are to be the raw material making with the impregnated paper of glue, and be nonflammable.

Embodiment of the present utility model is referring to Fig. 1, Fig. 2, Fig. 3.

Fig. 1 is a cutaway view, 1 arrow, 2 parachutes, 3 rocket bodies, 4 sleeve pipes, 5 adaptive circles, 6 grabs, 7 whole empennages, 8 engines.

Fig. 2 is that the A-A of Fig. 1 is to upward view.

Fig. 3 U type grab schematic diagram.

This model rocket and denomination of invention are: the manufacture method of model rocket engine, the supporting use of the patent application of application number 92102249.2.Can be made into and the supporting series model rocket of motor power size.

During making, arrow, whole empennage are the raw material single injection-molded with engineering plastics, the link of one connection parachute is arranged at the arrow bottom, rocket body is for making cylindrical body according to rocket size helical coil, and the pretightning force that gives 0.5～1 kilogram guarantees the requirement of its intensity and profile, arrow is inserted an end of rocket body, and the other end of rocket body inserts in the connecting tube of whole empennage.Make the various sleeve pipes supporting with engine, by the adaptive circle that is suitable for sleeve pipe and rocket body sleeve pipe and rocket body are combined as a whole in bonding mode, each one up and down on the adaptive circle of fixed sleeving is protected positive parachute-opening agent and is not leaked and can rapidly umbrella be opened from the rocket bottom.

During emission, at first hitch the link of arrow with the connection cord of parachute, the fag end that throws away connects together with adhesive plaster and rocket body inwall, a little fire-retardant chip of in rocket body, packing into then, with the parachute rocket body of packing into, insert good arrow, electric igniter is filled in and is broken grab behind the engine jet pipe gently into two with one's hands with the engine sleeve pipe of packing into, grab blocks the engine bottom, deenergization is connected lead and is placed on the launching tower, personnel leave the launch site, and transmitter control station is issued operational order automatically, countdowned, controls the folding of launching tower movable platform, the rocket firing lift-off.Parachute is opened automatically after being raised to certain altitude,

The diameter of this model rocket can be greatly, can be little, rocket body can be high, can be short, maximum gauge can reach 90 millimeter, and is high about 1.3 meters, penetrates high 50～60 meters.
