That can't be a good thing for the Lynx program.. Easy on the doom and gloom . The 5H25 was a development engine that we tested in 2015, and while the technology is similar, it isn't part of the Lynx program. This engine and pump were built for ULA as a subscale demonstrator for the 8H21. Also, as I understand it, the hardware isn't a permanent display and we sent it to them just for the conference.
How's it going with 8H21, are you making good progress?. Any ETA of test firing?

Why 5H and 8H?
The company, however, claims it has not abandoned the Lynx. The hardware built for the Mark 1 prototype vehicle remains in the company’s Mojave, California, facility, where a handful of employees are performing a “system review and documentation effort,” company spokesman Marco Martinez-Venturi said in March.
Martinez-Venturi acknowledged that additional progress would depend on the company’s ability to raise more money. “Although we have advanced the program with much of our recent efforts, completion of the prototype is funding dependent,” he said. “The start of the test flight program, like the vehicle completion, is dependent on funding.”
He did not respond to a request for an update on Lynx in May.
On Friday, President Donald Trump announced his intent to nominate [Jay] Gibson to be deputy chief management officer of the Department of Defense.
Quote from: baldusi on 04/07/2017 08:50 pmWhy 5H and 8H?XCOR uses a number/letter/number format for engine designations. The first number is the thrust class of the engine, the letter is the propellant combination (LOX/hydrogen in this case), and the second number is the design number.
So "8H21" is an 8000 lb thrust, Hydrogen fuel, design number 21 on the internal XCOR project index?
Quote from: john smith 19 on 06/21/2017 12:06 pmSo "8H21" is an 8000 lb thrust, Hydrogen fuel, design number 21 on the internal XCOR project index?Almost, the 8H21 is designed to be a 25,000 lb thrust engine. The 8 refers to the "thrust class", which is an internally designated range of thrust values. I don't think we have ever published the specific thrust ranges, but basically each successive number covers a higher range of thrust values.
XCOR Lays off Remaining EmployeesJuly 5, 2017 Doug MessierStruggling XCOR Aerospace has laid off its remaining employees in Mojave, Calif. and Midland, Texas.“Due to adverse financial conditions XCOR had to terminate all employees as of 30 June 2017,” the company said in a statement. “XCOR management will retain critical employees on a contract basis to maintain the company’s intellectual property and is actively seeking other options that would allow it to resume full employment and activity.” [...]
Gibson managed find himself a nice passing ship to jump to. So much for captain going down with the ship. ULA may have to step up if they want their ACES engine. Either buy rights to it and bring it in house or pass it on to likes of Masten.
