The importance of reliable and efficient launch vehicles pervades the many industries which rely on space based hardware. An experimental investigation has been performed into the effects of nozzle length and exhaust plume presence on a FESTIP axisymmetric base flow at Mach 0.7. Three different nozzle lengths (L/D = 0.6, 1.2, 1.8) were tested to...

During the launching vehicles design and their optimization process, the implementing of aerodynamic characteristics (AC) database is quite important. Accuracy of such database determines quality of the pre-flight simulation, trajectory and even the whole design direction. However, the database building process is one of the most challenging...

An end-to-end simulator for frequency scanning methods of filtered Rayleigh scattering (FSM-FRS) has been developed during the master thesis research at the German Aerospace Center (DLR). It can model several frequency scanning filtered Rayleigh scattering methods and predict the accuracies in measuring flow temperature, pressure, and velocity....

Any reduction in vehicle drag or fluid resistance provides a potential of substantial energy savings, with obvious benefits to the economy, environment and overall industrial competitiveness. Although various experimental studies have confirmed the potential drag reduction of dimpled surfaces in a turbulent boundary layer (BL), the working...

Oblique Shock-Wave Reflections or Shock Wave-Boundary Layer interactions (SWBLI) are complex phenomena which commonly occur in high speed flight. SWBLIs can have catastrophic consequences on the aircraft due to shock induced separation and unsteadiness of the interaction. These adverse effects can be mitigated by manipulating the boundary layer,...

With a growing demand for cheap access to space and high-speed flight, hypersonic research is experiencing an unceasing interest from worldwide parties. The vehicles designed for this purpose experience flight conditions where real gas effects caused by dissociation and ionization of the air molecules greatly influence the flow conditions and...

In a previous study, the optimal re-entry trajectory of Hyperion-2 has been derived. The mission of the vehicle is to measure hypersonic boundary-layer transition, a phenomena in which the laminar boundary layer turns into a turbulent boundary layer. This is an important feature in hypersonic flow to investigate, as it introduces peak heating...
