The Aerodynamics, power and propulsion laboratory houses a number of high-speed and low-speed wind tunnels for aerodynamic measurements, including a 1.25x180m low-turbulence wind tunnel, a 2.85x2.85m open jet facility and a 0.27m diameter hypersonic facility. In addition a combustor research lab and organic Rankin cycle test facility being built.

The AWEP department Aerodynamics, power and propulsion laboratory is spread over two locations: the Low-speed wind tunnel laboratory (LSL) and the High-speed laboratory (HSL).
The LSL activities involve 4 wind tunnels, of which the LTT, the low-turbulence tunnel, is the most known. Due to its good flow quality and its 1.25x1.80 m test section it is e.g. frequently used as an international reference facility for airfoil measurements. The 0.6 m diameter V- (vertical) tunnel is being modified to become a test facility for noise measurements (new AWEP chair) and the G- (boundary layer) tunnel will be modified to become an additional 0.6x0.8 m cross section regular wind tunnel for PhD work and educational purposes.
The HSL contains 4 high speed wind tunnels ranging from transonic to hypersonic flow next to the Open jet Facilty (OJF) and the W-tunnel for low speeds. The hypersonic wind tunnel (HTFD) is one of the few in Europe based on the so-called Ludwig-tube principle which make it possible to reach Mach numbers between 6 and 11. The OJF is the biggest facility. It has an open jet of 2.85 x 2.85 m which enables us to do measurements on high blockage models such as rotor models and propellers. Next to measurements in the aerospace domain this tunnel is also used by TUDelft Dream Teams such as the Human Power Team and ECO-Runner and as test facility for drag reduction in elite sports.
Power and Propulsion test stands
Since 2013 a new chair in the section FPP is erected aiming at the development of innovative propulsion and power subsystems. The associated facilities, a test setup for flameless combustion and an Organic Rankine Cycle power system research facility are being constructed in the HSL next to the Hypersonic wind tunnel.
The laboratories are o.a. equipped with state-of-the-art high precision pressure measurement and PIV equipment (including high speed lasers and camera’s).
