1966 TRIUMPH IRS ROADSTER - €38,950
On the 6th September 1966 Triumph UK was commissioned to build this TR4 IRS for its first owner a Mr. J.R. Davis who worked out of the U.S. Naval Research Lab in Washington D.C. The car was shipped out aboard the SS Lohengrin and arrived Stateside on the 13th November 1966. After 16 years he sold the car on to a Mr. Goldman in early 1980. Mr. Goldman only kept the car for a year when he sold it to a Mr. Tucker. The Triumph then stayed in longterm ownership of the Tucker family for 38 years. In 2017 invoices totalling $5,000 evidence major maintenance carried out to the Triumph. This TR4 IRS has only had 3 owners in 54 years. No less remarkable is the amount of documentation that comes with this car. The first bill of sale, the communication between the client and Triumph UK, the invoices, the brochure, the workshop manuals and a notebook with mileage and fuel use all form part of the extensive documentation. As if this is not enough, the car s
What if Space Junk and Climate Change Become the Same Problem?

It’s easy to compare the space junk problem to climate change. Human activities leave too many dead satellites and fragments of machinery discarded in Earth orbit. If left unchecked, space junk could pose significant problems for future generations rendering access to space increasingly difficult, or at worst, impossible.
Researchers advance detonation wave propulsion for hypersonic flight
Researchers from the University of Central Florida and the US Naval Research Laboratory have discovered an experimental configuration and flow conditions that generate a stabilized oblique detonation a phenomenon that has the potential to revolutionize high-speed propulsion of the future. An open-access paper on their work is published in
Proceedings of the National Academy of Sciences (PNAS).
Future terrestrial and interplanetary travel will require high-speed flight and reentry in planetary atmospheres by way of robust, controllable means. This, in large part, hinges on having reliable propulsion systems for hypersonic and supersonic flight. Given the availability of fuels as propellants, we likely will rely on some form of chemical or nuclear propulsion, which means using various forms of exothermic reactions and therefore combustion waves. Such waves may be deflagrations, which are subsonic reaction waves, o
Flying at Speeds up to Mach 16 Could Become Reality
In their latest research published Monday in the journal
Proceedings of the National Academy of Sciences, the researchers discovered a way to stabilize the detonation needed for hypersonic propulsion by creating a special hypersonic reaction chamber for jet engines.
“There is an intensifying international effort to develop robust propulsion systems for hypersonic and supersonic flight that would allow flight through our atmosphere at very high speeds and also allow efficient entry and exit from planetary atmospheres,” says study co-author Kareem Ahmed, an associate professor in UCF’s Department of Mechanical and Aerospace Engineering. “The discovery of stabilizing a detonation the most powerful form of intense reaction and energy release has the potential to revolutionize hypersonic propulsion and energy systems.”
