Press Release

Physical Sciences Inc. (PSI) has been awarded a program from the U.S. Air force to continue development of its Additive Manufacturing (AM) plus brazing process that allows duct segments and other components to be joined together into large-scale, highly complex scramjet assemblies.

The Air Force requires large scale scramjet engines but current fabrication methods have long lead times, high part rejection rate, and great expense due to hand-rework by skilled fabricators. PSI’s method makes it possible to combine many pieces of potentially differing materials together into a leak-free whole. Different metals can be used, as can dissimilar materials such as ceramic and metal. This method makes use of PSI’s previously developed heat exchanger geometry, which has resulted in four times reductions to the weight of airborne heat exchangers.

PSI’s technology is applicable to scramjets, ramjets, rotating detonation engines and rockets, and propulsion applications that have similar requirements. It applies to joints between other power and thermal components such as heat exchangers, hot structure, flow liners, and aeroshells. This technology has immediate application to military and space vehicles. Commercial markets include aerospace and ground engines of all types. It will reduce scramjet engine lead times by 50% and part production costs by 50% due to parts count reduction, and is an enabler for large scramjets.
