The work aims to study the application of HolyPan composites in medium-sized airdrop systems through analyzing the existing problems of medium-sized airdrop systems based on research of properties of HolyPan composites. Firstly, the impact resistance, tensile strength and suspension strength of HolyPan composites were tested respectively. Secondly, the HolyPan composites were applied as main body materials to carry out an improved design of medium-sized airdrop systems in service. Finally, a drop buffer test was conducted on the designed samples to verify the rationality of applying HolyPan composites in medium-sized airdrop systems. As a result, the medium-sized airdrop platforms and containers with main body of HolyPan composites were significantly superior to medium-sized airdrop systems in service in terms of buffer performance. In conclusion, the application of HolyPan composites in medium-sized airdrop systems has practical significance, which can significantly improve the safety and reliability of medium-sized airdrop systems.
