Research on structural design and test technologies for a three-chamber launching device.

Area of Science:

• Mechanical Engineering
• Ballistics
• Materials Science

Background:

• Existing launching devices face limitations in achieving high projectile velocities and kinetic energy.
• Investigating kinetic energy weapons requires platforms capable of launching projectiles at extreme speeds.

Purpose of the Study:

• To develop and validate a novel three-chamber launching device for enhanced projectile acceleration.
• To enable high-speed projectile testing for various shapes and quality levels.
• To support research into kinetic energy weapons and their effects.

Main Methods:

• Design and development of a three-chamber barrel with horizontally placed auxiliary chambers.
• Implementation of a secondary acceleration mechanism using ignited combustible gas from auxiliary chambers.
• Addressing key design challenges including chamber axis angles, propellant charge, gas sealing, and sabot/belt design.

Main Results:

• Successful validation of the three-chamber device through launching and engineering protection tests.
• Demonstrated ability to launch projectiles with high initial velocity under low bore pressure.
• Achieved approximately 15% increase in average launching velocity and 35% increase in muzzle kinetic energy compared to single-chamber devices.

Conclusions:

• The proposed three-chamber launching device is effective for high-speed projectile tests.
• The device offers significant improvements in velocity and kinetic energy for small-caliber firing tests.
• The design is robust, with verified structural integrity and reliable sealing for demanding applications.
