To maintain ecological conservation and species balance, it is necessary to utilize shooting sterilization vaccines to manage the issue of overpopulation among species. Therefore, exploring the application of shooting devices is crucial. The key to effective deployment lies in designing these devices to achieve an effective range while minimizing the distress caused to animals during vaccination. This study explores the use of high-pressure air for shooting device applications, utilizing the differential pressure between high-pressure air and atmospheric pressure to provide an initial flight velocity to a syringe loaded with vaccine. The force with which the syringe is fired is affected by variations in pressure and barrel length, which are related to the internal energy of high-pressure air and the gas expansion ratio during the expansion stroke. The research involves conducting multiple simulations and experiments with various barrel lengths and storage pressures to determine the optimal length and pressure relationship under fixed volume conditions. Additionally, unmanned rotorcrafts are utilized as tools for air-to-ground operations. To reduce the payload weight on unmanned aerial vehicles, resonant waves are also integrated into the study. Resonance within the barrel can minimize the use of barrel length and gas pressure, achieving task completion with minimal equipment resources. The application of shock wave shooting devices can potentially be extended to various fields in the future, such as ecological diagnostics of trees, real-time environmental testing, and cold launches in military engineering.
