| Abstract: |
| Objective To study the landing environmental worthiness of airborne equipment. Methods Based on finite element method, response surface and Monte Carlo method, the successful landing probability was predicted. The influence of different landing velocity, land surface slope and surface wind on the successful landing probability was studied. The landing environmental worthiness data of airborne equipment was analyzed, and the measures for improving landing environmental worthiness of airborne equipment were proposed. Results The results proved that vertical velocity and surface wind had significant influences on the probability of success, while the surface slope had insignificant influence. Conclusion The successful landing probability could be predicted based on the research on landing environmental worthiness. The results could provide theoretical reference and technical guidance for airdrop. |
