Abstract

A launching method of a spacecraft relates to the aerospace technology field, aiming to solve the technical problem that the existing spacecraft has high launching cost. The method is characterized inthat firstly a small solid rocket carrying the spacecraft is suspended on the lower part of an unmanned balloon, the balloon is used to carry the rocket to a preset position of the stratosphere, therocket is separated from the balloon through wireless instruction, then the rocket is ignited to launch through wireless instruction and the rocket sends the spacecraft to the preset space orbit. Thelaunching method provided by the invention is simple and feasible and the launching cost can be reduced.

Description

The launching technique of spacecraft

Technical field

The present invention relates to space technology, particularly relate to a kind of method that spacecraft is emitted to space.

Background technology

Present spacecraft generally all is to be emitted to space from ground with large-scale carrier rocket, spacecraft is succeeded in sending up, must overcome the own wt of rocket and spacecraft, and the very short solid-rocket of combustion period will pass through dense atmospheric envelope from the ground surface launching, can make rocket flight speed be subjected to very big loss, flying height descends greatly.Therefore the launch site of spacecraft generally all is chosen in height above sea level is higher, density of air is thinner relatively highlands to save launch cost.

Another kind method be to use large transport airplane with the delivery of pencil rocket and spacecraft to the high-altitude (advection layer), utilize then this pencil rocket from aerial emission spacecraft to space.This launching technique has not only promoted the initial transmissions height, and air resistance also significantly reduces, thereby greatly reduces the demand to total thrust, has greatly reduced the amount of carrying of propellant, and is therefore much lower than the launch cost that ground launch mode spent.But employing pencil rocket that large transport airplane will be loaded with spacecraft is transported to the advection layer high-altitude and still need spends substantial contribution, and transport plane need be made the acrobatic maneuver that promptly rises to after throwing in rocket from the high-altitude, rocket is separated fast with aircraft, withdrawing to the safety zone rocket on transport plane could light a fire, therefore this launch mode is very high to transport plane and aviator's requirement, has certain enforcement difficulty.

Summary of the invention

At the defective that exists in the above-mentioned prior art, technical matters to be solved by this invention provides a kind of simple, and can save the launching technique of the spacecraft of launch cost compared to existing technology.

In order to solve the problems of the technologies described above, the launching technique of a kind of spacecraft provided by the present invention, it is characterized in that: the small-sized solid-rocket that will be equipped with spacecraft is suspended on driverless operation balloon below, and utilize balloon that it is delivered to stratospheric desired location, by radio command rocket is separated with balloon again, and then make rocket firing emission by radio command, by rocket spacecraft is sent into predetermined space track.

The launching technique of spacecraft provided by the invention, utilize balloon that rocket is delivered to advection layer and carry out high-altitude input emission, not only promoted the initial transmissions height, and air resistance also significantly reduces, thereby can greatly reduce demand to total thrust, therefore can reduce the size and the weight of rocket, can reduce the launch cost of spacecraft, and it be also lower to implement difficulty.

Description of drawings

Fig. 1 is the schematic diagram of launching technique of the spacecraft of the embodiment of the invention.

The specific embodiment

Below in conjunction with description of drawings embodiments of the invention are described in further detail, but present embodiment is not limited to the present invention, every employing analog structure of the present invention and similar variation thereof all should be listed protection scope of the present invention in.

As shown in Figure 1, the launching technique of a kind of spacecraft that the embodiment of the invention provided, it is characterized in that: the small-sized solid-rocket that will be equipped with spacecraft is suspended on driverless operation balloon below, and utilize balloon that it is delivered to stratospheric desired location, by radio command rocket is separated with balloon again, and then make rocket firing emission by radio command, by rocket spacecraft is sent into predetermined space track.

Add one-stage rocket when the ballistic performance that adopts balloon borne rocket to obtain in the high-altitude emission is equivalent in the ground surface launching, it uses altitude range generally at 100～200 kilometers, can be used for the detection of physical phenomenons such as cosmic ray, geomagnetic field and aurora.

Claims

1, a kind of launching technique of spacecraft, it is characterized in that: the small-sized solid-rocket that will be equipped with spacecraft is suspended on driverless operation balloon below, and utilize balloon that it is delivered to stratospheric desired location, by radio command rocket is separated with balloon again, and then make rocket firing emission by radio command, by rocket spacecraft is sent into predetermined space track.
