Introduction
The missing understanding of the disintegration of spacecraft structures during the atmospheric entry flight is the main driving parameter for the calculation of ground impact risk. Additionally, the full demise of the spacecraft becomes increasingly important, because of the rapidly increasing number of Low Earth Orbit (LEO) which undergo uncontrolled entry after the...
Ground testing has always been essential for aerospace development. As an example, they are a key component in the design process and qualification of thermal protection materials for re-entry systems. They also have a crucial role to tackle the problem of space debris for which the end-of-life disposal through aerothermal demise in atmospheric entry is largely promoted. In such context,...
Background of the study
Thanks to the improvements performed in the application of the dual-colour pyrometers for the temperature measurement of the exposed surface of the samples at the hot hypersonic plasma, now it is possible to analyse qualitatively the trend of the material surface spectral emissivity of a sample or an assembled model during the development of a test run carried out...
Investigation of plasma radiation in an arcjet driven facility is demanding due to severely limited optical access and very dynamic processes. This complicates volumetric measurements, which are important for the understanding of many flow phenomena. In this paper, we present our recent advancements in the field of light field deconvolution. Originally developed in the domain of microscopy,...
In the future, Air-Breathing Electric Propulsion (RAM-EP) systems may enable low-altitude missions over long lifetimes. The European consortium “AETHER” is currently designing a RAM-EP prototype for ground testing. In the context of this project, an experimental effort has been conducted to characterize the Particle Flow Generator (PFG), which is responsible for providing the RAM-EP system...
