The lightest and the most efficient heat exchanger for the DASS GN1 and DASS GNX air breathing engines are made with no joints, no welds, no brazing, and no mechanical connections. It is built from various exotic metals including titanium. It uses liquid hydrogen and nano-particles for cooling. The same is also used along with regular jet fuel as a fuel too. No frost.
Space Engine Systems’ DASS engine technology (patent pending) utilizes multiple fuels to achieve efficient propulsion from rest to hypersonic speeds in an environmentally friendly manner. The focus of the company is the development of DASS GNX propulsion system to power a reusable single-stage-to-orbit vehicle and DASS GN1 propulsion system to power hypersonic cruise vehicle. To demonstrate this technology, a ground testing facility which can simulate the high-temperature and high-altitude air conditions that occur after the supersonic intake is under development. The facility is highly modular and can easily be adapted for many applications.

Space Engine Systems Inc. is building the world’s first Full Scale Multi-fuel test facility for air breathing engines. This test facility will test combined multi-fuel in off the shelf air breathing engines with liquid hydrogen, jet fuel, and nano-particles of boron under full scale testing with the state of the art lightest and most efficient heat exchanger and afterburner for aerospace and space applications. The combination of these fuels has never been done in an air breathing engine until to date except by Space Engine Systems Inc. The technologies are patent pending at this time. The final full scale testing of the DASS GN1 Supersonic engine – 30 kms altitude (Aerospace) will be completed by Q1 2017. The DASS GNX for Space applications with stored oxygen under full load are on schedule for the later part of 2018.
