Embodiment 1

[0034] This embodiment provides an airborne drop-drop sounding pod reliability evaluation system, such as figure 1 As shown, it includes a thermobaric chamber 105 , a wind unit 104 and a vibration table 101 , and both the wind unit 104 and the vibrator 101 are arranged in the thermobaric chamber 105 . The thermobaric chamber 105 has temperature and air pressure control functions, and is used to provide a low temperature and low pressure environment for simulating the pod at high altitude. For example, the indoor temperature can be adjusted between -90° C. and 25° C. through the temperature and pressure regulating chamber 105 , and the indoor air pressure can be adjusted between 500 hPa and 1050 hPa. The wind unit 104 is used for simulating the wind force when the pod is flying at high altitude, and can generate uniform and stable wind force with adjustable wind speed. The shaking table 101 is used to simulate the vibration environment suffered by the pod when it is launched o...

Embodiment 2

[0044] This embodiment provides a reliability assessment method for an airborne drop-drop sounding pod, image 3 It is a flow chart illustrating the reliability evaluation of the pod based on the evaluation system provided in the first embodiment according to some embodiments of the present invention. Although the processes described below include a number of operations in a particular order, it should be expressly understood that the processes may include more or fewer operations, which may be performed sequentially or in parallel. like image 3 shown, including the following steps:

[0045] S101. Acquire the pressure, temperature, wind force of the surrounding environment, and vibration of the airborne platform when the pod to be evaluated works.

[0046] Statistical investigations have found that when the airborne dropsonde pod drops the sonde, it is mainly affected by environmental factors such as temperature stress, air pressure stress, wind resistance stress formed by ...

Abstract

The invention relates to the field of meteorological detection, in particular to an airborne drop sounding pod reliability evaluation system and method, and the system comprises a temperature and pressure regulation chamber which is used for simulating the air pressure and temperature of the surrounding environment when a pod to be evaluated works; the wind power unit is arranged in the temperature and pressure adjusting chamber and is used for simulating the wind power of the surrounding environment when the pod to be evaluated works; the vibration table is arranged in the temperature and pressure adjusting chamber and used for fixing the to-be-evaluated pod and simulating vibration borne by the airborne platform when the to-be-evaluated pod works; and the circulating unit is arranged in the temperature and pressure adjusting chamber, is positioned beside the to-be-evaluated pod, and is used for recycling the sonde thrown by the to-be-evaluated pod and loading the recycled sonde into the to-be-evaluated pod. Compared with a comprehensive evaluation method, the evaluation system has the advantages that the evaluation cost can be reduced, the engineering practicalability is improved, the evaluation system can be suitable for rapid stability evaluation in the pod acceptance stage, and a safety guarantee is provided for stable operation of the airborne drop sounding pod.

Description

technical field [0001] The invention relates to the field of meteorological detection, in particular to a reliability evaluation system and method for an airborne drop-drop sounding pod. Background technique [0002] Airborne drop sounding pods are key equipment for high-altitude meteorological detection, widely used in research on climate change, meteorological science and extreme weather (such as typhoons, tornadoes, etc.), disaster and emergency meteorological support, weather modification, border weather management, Battlefield environment support, meteorological, marine and hydrological detection, long-range combat meteorological support, and marine and atmospheric waveguide diagnosis. With the vigorous development of the national marine strategy, airborne drop sounding pods as space-based meteorological facilities have gradually become mainstream equipment, but their delivery reliability has become an important factor restricting the success rate of drop sounding pods ...
