A procedure for optimizing the configuration of a heat pipe/fin radiating element in terms of heat rejected per radiating mass has been developed. The optimization was carried out analytically by expressing the heat radiated per radiating mass in ter

An algorithm for optimizing the fin geometry of a heat pipe/fin radiator with tapered fins has been developed and a test article has been fabricated from graphite reinforced fiber composite (GRFC) to test the model. The algorithm determines the width

Mercurous chloride is an acoustical optical material with an unusually low acoustic velocity and high acousto-optical figure of merit, which makes it an interesting candidate for optical delay lines and Bragg cells for optical signal processors. It a

One of the major stumbling blocks that prevents rapid structure determination using x-ray crystallography is macromolecular crystal growth. There are many examples where crystallization takes longer than structure determination. In some cases, it is

Contaminating fluxes from upper atmospheric molecules found in the wake of a typical spacecraft of the Long Duration Exposure Facility class are studied with the aim of determining vacuum levels which may be employed by experiments mounted on the veh

This induced environment consists of particles and gases which emanate from the spacecraft in orbit and form the 'contamination cloud'. The presence of the cloud can present certain problems connected with scattering effects and the deposition of con

The virtual absence of hydrostatic pressure in a microgravity environment allows liquids to be confined solely by their surface tension and offers the possibility of melting and solidifying materials without physical contact. This “containerless pr
