RotorSchmiede – ultralightweight / ultra sophisticated

The second RotorSchmiede VA250 ultralight has been manufactured. Now, we await to get the permit to fly very soon here in Germany. We are happy to use this helicopter for flight testing then.

Yesterday, the China Central Television CCTV visited us from its Berlin office in order to get some material for their report. It can be seen relating to the China International Import Expo 2021 in the next weeks. ... See more

Our helicopters arrived in Shanghai. Preparation of our booth at China International Import Expo can start now 🥳

New VA250 prototype - still waiting for PTF but ready for flight testing 🙂

It seems we are the first ⏰😁

Freight prepared for China International Import Expo

Great news: We are one big step closer to the PTF of the RotorSchmiede VA250 ultralight. We finished ground runs with in sum more than 30 hours as per German certification specifications. Rotor and control system were tested succesfully. Additonally, the propulsion and cooling systems also proved their reliability. We'll continue with structural testing of sub-assemblies now. ...

It should be summer again.

Measuring data for showing the efficiency of the VA250 cooling system.

As already known from the VA115, the VA250 follows our tradition of delivering unlimited hover time without any problems of engine overheating. The test was carried out within the certification programme, with the helicopter fixed to the ground. No external cooling systems, fans, airstream due to the flight etc. were used.

The engine revved up to nominal rotational speed followed by a short test of the freewheel unit. And after that, you can see over 40 minutes of full engine output power (pitch at maximum lift position). The engine cooling water temperature gets to a stable level quite fast while the gearbox oil temperature needs some time to get hot. Both are safely within limits so there's a lot reserve for summer conditions. We are happy about these results 🙂 ... See more
