Inventor Alexander Gurulev has received a patent for a utility model of a catapult for aircraft, according to a publication in the Rospatent database. The device is designed for launching drones and other flying objects from confined spaces.

The catapult includes a carriage, torsion springs, locks, a launch hook, a body, and a cocking mechanism. The main difference from existing spring catapults is a design that eliminates power loss during acceleration. In traditional systems, the spring force decreases as it extends, which reduces launch efficiency. The new development allows maintaining force throughout the entire acceleration phase.

Another advantage is the ability to adjust the carriage's acceleration. This is achieved by installing torsion springs of different stiffness. This makes the catapult versatile for launching devices of various weights and sizes. The device can be used in unmanned aviation, as well as in robotics and other areas where launching objects from confined spaces is required.
