Abstract

The small vehicle is ejected from the launcher using a catapult and strikes the target bull’s-eye following a parabolic flight. Modal analysis of the vehicle is conducted to avoid resonance before launch, which could affect the flight trajectory. In-flight flow field analysis is performed to study the vehicle’s flight attitude. Upon hitting the target, a strong impact is expected and landing will result in a significant collision. When the vehicle falls to the ground, it may be crushed by a wheeled robot. Finite element analysis is used to study the stress on the parts most likely to fracture, so they can be reinforced accordingly.
