Problems solved by technology

[0003] At present, the meteorological sounding rocket detection system equipped with parachute radiosonde, through the analysis of the 25 flight results of the system, the high-altitude low-density aerodynamic conditions are weak, and the deceleration effect of the parachute system is slightly insufficient after the rocket is separated. When the altitude is required to be 60km-70km, the speed reduction of the radiosonde cannot meet the requirements very well, and there are obvious interferences such as aerodynamic heating in the detection data, which affects the detection accuracy

Embodiment Construction

[0022] The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0023] The invention provides a rapid deployment umbrella system under high-altitude and low-density conditions, such as figure 1 As shown, it includes an active pull-type parachute system, a payload, a buffer belt 10 and a buffer rope 6 .

[0024] The active pull-type parachute system includes: main parachute, umbrella bag 1, umbrella rope bag 2, umbrella rope fixing belt, swivel joint 5 and lead rope 11; The top of the umbrella cover 3 is connected to the bottom of the umbrella bag 1 through the top rope 11, folded and placed in the umbrella bag 1, and the umbrella bag 1 is sealed by the umbrella rope 4; The rope bag 2 and the umbrella bag 1 are sewn together, and the umbrella rope 4 located outside the umbrella bag 1 is folded in half and passed through the umbrella rope fixing belt to limit it on the umbrella rope bag 2, which can ensure that the umbr...

Abstract

The invention provides a system for rapidly deploying an object umbrella under high altitude and low density condition, which comprises an active pull-down parachute system, a payload, a buffer band and a slow-moving Okinawa. The payload is connected with the active clockwise parachute system through Okinawa, the active clockwise parachute system is connected with the external arrow body through abuffer belt, and the payload is used as a power source to actively straighten the parachute, so that the active clockwise parachute system can be deployed in an orderly manner. The invention can realize the rapid deployment of the object umbrella system and enhance the system reliability, and meets the requirement of 60km to 70km high-altitude atmospheric detection.

Description

technical field [0001] The invention relates to the technical field of rocket sondes, in particular to a rapid deployment parachute system under high-altitude and low-density conditions. Background technique [0002] Using rocketsondes to directly measure the environmental parameters of the adjacent space is the most effective means of high-altitude atmospheric detection. The dwell time at the local level must not cause unnecessary interference to the radiosonde. [0003] At present, the meteorological sounding rocket detection system equipped with parachute radiosonde, through the analysis of the 25 flight results of the system, the high-altitude low-density aerodynamic conditions are weak, and the deceleration effect of the parachute system is slightly insufficient after the rocket is separated. When the altitude is required to be 60km to 70km, the deceleration of the radiosonde cannot meet the requirements very well, and there are obvious interferences such as aerodynami...
