The accumulation of space debris objects on Earth's orbit is raising environmental and
safety concerns yielding an urgent need to develop Design for Demise methodologies. Free …

In this work, we develop a new methodology for hypersonic multi-body free-flight
experimentation and conduct several tests to explore the aerodynamic separation of equal …

An experimental and computational investigation of the unsteady separation behaviour of
two spheres in Mach-4 flow is carried out. The spherical bodies, initially contiguous, are …

Aerodynamic force measurement in high-enthalpy flow is very important for the design and
optimization of hypersonic vehicles. Currently, impulse facilities are used for generating high …

Traditionally, expansion tube test times have been experimentally evaluated using test
section mounted impact pressure probes. This paper proposes two new methods which can …
