Abstract

The invention discloses a rocket shell accelerating bag, which consists of a bag cover, a bag bottom and an air current groove, wherein the bag cover is arranged on the outer surface of the rocket shell, and is arc-shaped; the arc-shaped bottom faces the head of a rocket; the bag bottom is arranged on the inner side of the bag cover; the air current groove is formed from the bag bottom to the tail of the rocket; the groove surface of the air current groove is an arc-shaped surface depressed into the rocket; the shell of the same rocket can be provided with accelerating bags which are distributed on the surface of the entire shell; and the same annular line of the rocket shell is required to be provided with at least two bags which are arranged symmetrically by taking the rocket axis as the axis. Due to the adoption of the rocket shell accelerating bag, the friction relation between a flying rocket and the atmosphere can be changed into a sliding relation, the rocket is accelerated, the thrust energy of the rocket is saved, the overall weight of the rocket is reduced, or the thrust force of the rocket is increased.

Description

Rocket envelope speedup bag

Technical field

The present invention relates to the design of rocket envelope shape, especially relate to rocket envelope speedup bag.

Technical background

Existing rocket envelope surface is level and smooth.Level and smooth rocket envelope surface will inevitably form viscous force with air when the rocket high-speed flight, reduce flying speed, increases the rocket thrust loss, wastes energy.

Summary of the invention

The objective of the invention is to provide a kind of viscous force between rocket body outer surface and air when eliminating rocket and in air, flying, and make above-mentioned viscous force become the rocket envelope speedup bag of rocket thrust, jointly consisted of by pkt. flap, the bag end and airslide.

Described pkt. flap is located on the outer surface of described storepipe, and is arc.The end of described arc, is towards the described rocket direction of arrow.

Be provided with the described bag end in the inboard of described pkt. flap.

Caudal directions from from the described bag end to described rocket is provided with airslide.

The transversal of described airslide groove face also is recessed arc in the described rocket, and the groove width of described groove is narrowed down by wide from the described bag end to groove tail direction, until mild the disappearance.

When arranging described speedup bag, should the symmetry take the axis of described rocket as axis install by described rocket.

The described speedup bag that arranges at the same loop wire of same described rocket should be no less than two, and is the symmetry setting.

Carry out intensive when described speedup bag is set at the whole shell of same described rocket, should keep the globality on the layout of described bag position symmetrical.

When shell is provided with the rocket launching of rocket envelope speedup bag of the present invention, the air-flow that air forms produces the resistance air-flow to aloft rocket, when the resistance air-flow arrives the described speedup bag sack line that is located on the arrow, the resistance air-flow is because of at the bottom of the support that loses suddenly housing pours into bag, the impact of formation at the bottom of to bag also just formed the thrust to rocket; When the backward rocket rear spray that rebounds at the bottom of the bag of described air-flow makes rocket obtain thrust with regard to another when going.

The invention has the beneficial effects as follows: make the relation of aloft rocket and air become slip by viscous motion, make rocket obtain speedup, saved the rocket thrust energy.

Description of drawings

Below in conjunction with drawings and Examples the present invention is described in further detail.

Fig. 1 is the rocket envelope front view that speedup bag of the present invention is installed.

Fig. 2 is that (analysing and observe) figure is looked on Fig. 1 left side.

Fig. 3 is Fig. 2 A--A cutaway view.

Fig. 4 is the schematic layout pattern of intensive layout speedup bag of the present invention on rocket envelope.

Among the figure: 1, rocket arrow, 2, the speedup bag, 3, airslide, 4, rocket body, 5, pkt. flap, 6, the bag end, 7, the groove tail, 8, the sack line.

See Fig. 1, Fig. 2, Fig. 3 and Fig. 4, be provided with speedup bag 2 at rocket rocket body 4.Speedup bag 2 is made of jointly pkt. flap 5, the bag end 6 and airslide 3.The transversal at the end of airslide 3 curved (seeing Fig. 3).The sideline of airslide groove tail 7 is connected gently with rocket body 4.

See Fig. 2, when rocket flight, rocket arrow 1 is subject to air drag (seeing among the figure shown in three arrows of a row), and the air-flow that the resistance air forms moves along direction shown in the dash-dot arrows along the both sides of rocket arrow 1.After the air-flow of described motion arrives sack lines 8 through pkt. flap 5, air-flow because of lose support to pour into bag at the bottom of 6, formation is to 6 impact at the bottom of the bag, rocket also just obtains thrust.

Return rapidly after 6 stop at the bottom of said flow is subject to bag, and move along airslide 3 along direction shown in the heavy line arrow among the figure, finally rush at rocket body 4 ambient air layers, form again the motive force to the rocket rocket body.

Therefore can affirm, described speedup bag has good accelerating function to aloft rocket.

If described speedup bag is set on storepipe, should according to the schematic diagram layout designs among Fig. 4, make the described speedup bag between adjacent row staggered on a large scale.This both had been conducive to increase the intensity of rocket rocket body, also was conducive to described speedup bag and caught air-flow thrust, so that the air-flow of the rocket rocket body outer surface of will flowing through to greatest extent becomes the thrust of aloft rocket.
