Schedule

In an emergency, it may be vital to gather information in an environment that is dangerous to human rescue workers. An unmanned aircraft, such as an Unmanned Aerial Vehicle (UAV) helicopter, is increasingly valuable for a search and rescue operation.

However, UAV helicopters have launch requirements. If the launch could be performed remotely, the helicopter could be deployed efficiently without endangering rescue personnel.

We decided to design a method of remotely launching a UAV helicopter and build a prototype of our design. The launching apparatus and helicopter would be towed to the launch site by a remote-controlled ATV, and the launching apparatus would protect the helicopter while it was being towed. Once at the launch site, the apparatus would release the helicopter and provide a secure launching surface for the UAV helicopter.
