After a break I'm back now with an update on the project. In the mean time some work has been done on the project. Basic navigation software and ground station communication has been completed. Implementing the parachute ejection mechanism was quite a challenge because of the limited space on the plane. Finally after testing a bunch of concepts a working solution comes up. A hot gas propelled latch releases now the lit on the parachute bay.
The plane is ready now for the first fest flight from low altitude. Therefore I’m looking for an Quadrocopter pilot who likes to support the project and can lift the Near Space Plane to a suitable altitude for releasing it. A servo based release mechanism is already available. The weight of the plane is approximately 450 g.
