Abstract
Description
Technical Field
[0001] This invention relates to the field of model design, and in particular to a dangerous gas detection missile and its ejection system. Background Technology
[0002] Existing unpowered missiles consist of a warhead, a missile bay, a tail section, fins, and a parachute. The warhead is bullet-shaped to reduce drag and incorporates shock-absorbing structures to prevent fragmentation. The missile bay carries mission equipment to fulfill mission requirements. Tail fins are fixed to the tail section to stabilize flight attitude. The parachute slows descent and protects the mission payload. However, because the missile's outer shell is sealed and the mission payload is located entirely within the missile bay, the gas exposure to measuring instruments is limited, resulting in unreliable measurement values.
[0003] Existing cylindrical catapults consist of a launch frame, launch tubes, a gas storage device, a gas filling device, and an electrical control box. The launch frame is a rectangular frame with a rotating structure, allowing for free adjustment of the launch angle. The launch tubes are aligned at both ends and arranged parallel to each other on the launch frame. Inside each launch tube is a piston, end cap, and aircraft mounting bracket; the end cap is connected to a solenoid valve. The gas storage and filling devices provide the launch tubes with gas at a specified pressure. The electrical control box enables switching between cluster launch and single-tube launch, allowing for both all launches and individual launches. The multiple launch tubes of the catapult share the same gas tank, and the launch angles of all launch tubes are the same, making it difficult to rapidly launch missiles at various angles and pressures in unmanned environments. Furthermore, existing catapults are designed for use in low-wind, hard-surface environments and are unsuitable for deserts and high-wind conditions. Summary of the Invention
