The Reliability Design of Automatic Open-Parachute-Device

Abstract:

Automatic open-parachute-device is an essential device in the field of aviation life-saving technology. In this paper, on the basic of the open-parachute-device mechanism, structure of its reliability function is given. According to its reliability indicators, considering the main failure mode and combining with similar products' reliability statistical data, analysis and design of reliability indicators are processed. Successively according to the principle of "redistribution method" and the principle of "proportional distribution method" about failure rate, the reliability indicators are calculated in detail. The results showed that the reliability indicators allocation with the "proportional distribution method" is little different from the reliability indicators allocation with the "redistribution method", but the former is more in line with the requirements. This design has a guiding significance to the product production.
