AI Technical Summary

Technical Problem

When the existing aerodynamic ejection frame ejects a large-weight drone, due to the imbalance of air pressure, the speeds on both sides of the aircraft are inconsistent during takeoff, which affects the takeoff posture and even leads to a crash.

Method used

A double-tube ejection frame is designed, using a high-pressure gas storage cylinder group as the power source, connected to the two ejection tubes through a gas separation valve, and the piston block arranged in each ejection tube and its connected traction search mechanism are achieved to achieve efficient energy transmission. The dynamic balance component uses a speed detection module and a resistance adjustment actuator to ensure the consistent traction cable speed on both sides.

Benefits of technology

Through the design of the double-tube ejection frame, the thrust and stability are enhanced, the speed inconsistency caused by air pressure imbalance is solved, the accuracy and safety of the take-off attitude are improved, the maintenance process is simplified, and the maintenance cost and time are reduced.
