Sportavia RPV

from Wikipedia, the free encyclopedia

The Sportavia RPV was a drone development by Sportavia-Pützer from 1976.


The development of a "Remote Piloted Vehicle" (remote controlled drone) at Sportavia-Pützer took place in 1976 on behalf of the parent company VFW-Fokker , where an unmanned combat aircraft (UKF) was to be built since the early 1970s. Sportavia-Pützer was already involved in this project with the Sportavia S-5 and C.1 to study the location of such aircraft . As a follow-up order, Sportavia-Pützer received a study order from VFW-Fokker for the development of a transport drone called RPV that is difficult to locate.

The drone was designed for a single use with a payload of 500 kg and a flight speed of 200 km / h and was composed of lightweight elements for assembly under field conditions. The construction was made in GRP and wood construction with minimal metal components and was given a pusher nacelle above the wing that was largely insulated against noise and heat emissions. The engine was a 70 hp BMW R100 RS two-cylinder four-stroke engine with an exhaust gas charger. At the start, the RPV was placed on a launch vehicle. The launch vehicle could optionally be equipped with a LAR-1 solid fuel rocket from Dynamit Nobel to shorten the launch distance, which shortened the launch distance to 55 m. As further launch options, catapult launches, vertical launches with hot water rockets and winch launches should be examined as part of the RPV development.

The plan was to start RPV development in 1978 after the flight tests of the remote-controlled test vehicle Fiat G.91R at VFW-Fokker. The series recording should take place in 1984. However, the RPV development at Sportavia-Pützer did not get beyond the preliminary study and was later abandoned.

Unless otherwise stated, the information on the Sportavia-Pützer RPV drone was taken from.
