An array spring type drop door simulation load table for in-place release
By simulating a load platform with an array of spring-loaded delivery doors, and utilizing spring loading and a hook-and-wheel mechanism, the problem of load variation and timing simulation of delivery doors on firefighting aircraft was solved. This enabled simulation of high load density and door closing without load, making it suitable for performance testing of delivery doors on firefighting aircraft.

Abstract
A spring-loaded array-type release hatch simulation load platform is disclosed. The simulation load platform includes a frame, a hatch simulation component, an actuator, a spring loading device, and a fixed shaft. The spring loading device includes a hook wheel, an outer wheel, and a loading spring. The hatch simulation component is connected to the frame via bearings and mounted on it. The actuator is connected to the frame via a spherical bearing and mounted between the hatch simulation component and the frame. The hook wheel of the spring loading device is connected to the rotating shaft of the hatch simulation component via a key, and the two ends of the loading spring are connected to the hook wheel and the outer wheel, respectively. According to the loading torque requirement, an even number of spring devices can be installed symmetrically. The outer wheel of the spring loading device is fixedly connected to the frame via a fixed shaft.
