Delft University of Technology Testing Unconventional Aircraft

With the engines at the back and the tail wings folded around it has developed a new type of aircraft the TU Delft. The Unit flew its first laps on Woensdrecht Airport.

“The fly behavior was beyond expectation” says an enthusiastic prof. dr eng. Leo Veldhuis, Professor of Flight Performance & Propulsion at the Delft University of Technology after the test flight with a model of the plane he designed. The industry, including Airbus, asked him to design an efficient and unconventional aircraft.

Unconventional is the Delft University Unconventional Configuration (PASH) certainly become. The unit, meant for distances up to 1000 km, propeller propulsion. Field House: “That is on that shorter distance more efficient than a Jet engine, it saves about 20% in fuel consumption.

The engines sitting at the back because they perform best that way

Disadvantage of propellers is that they are noisy, and came up with an innovative idea: screen Field House the propeller with a ring wing, which at the same time serves as tail wing. Tail surfaces at the back of the ring wing provide the control and serve as highs and rudder.

A scale model of the device is created, with which early this summer the first test flights are made on Woensdrecht Airport.. That went beyond expectations. There are new tests, in which, for example, one of the engines is turned off during the flight. “We want to know more about the stability of our concept.”

Expire the tests as good, then the next step that funding must be found to further development in PASH Project.
