To determine the effects of propeller ducts on quadrotors in longitudinal forward flight, using flight data and stepwise regression

In order to gain more insight into the effects of propeller ducts on quadrotors in forward flight, this research analyses flight data obtained from free flight tests, performed in the Cyberzoo and the Open Jet Facility of the TU Delft. Using a quadrotor platform with detachable propeller ducts, both trimmed forward flight tests and flights...

The longitudinal handling characteristics of the Skysurfer X8

For decades the physical appearance of aircraft remained more or less unchanged. The increase in efficiency which still can be made by improving this design, is limited. More researchers have started to investigate new design options that represent a departure from established concepts. The main drivers behind these endeavors are the tightening...

Determining the lateral-directional handling characteristics of a Skysurfer X8

With standard aircraft configurations reaching their limits in efficiency, new aircraft configurations are being theorized and analyzed. One type of analysis is remotely piloted scaled flight tests. One of the aspects that can be analyzed through remotely piloted scaled flight tests is the dynamic behavior of the aircraft. This thesis shows a...

Analysis of fluid motion in cryogenic propulsion upper stage tanks during launcher ascent phase

The graduation project was conducted at the upper stage liquid propulsion department of ArianeGroup at the facilities of Airbus DS, Bremen. Based on a series of past flights of Ariane 5 launcher, the aim is to analyze the fluid motion and the pressure fluctuations in the cryogenic propulsion upper stage Liquid Hydrogen (LH...
