George Allegrezza said:Ah, they're screwed. From the BAA:
The propulsion system for the S&T technology demonstrator weapon must include an air-breathing engine capable of supersonic combustion.
And they want the demo to be "evolvable to TRL 7+". Good luck with that. I'm mystified as to why they specified a specific technology for the propulsion system. It would have been easier to specify performance targets and let the contractors demo whatever works.

DSE said:bobbymike said:I agree let's have a good old fashion hypersonic solid fueled rocket, which we could have sooner rather than later, and then develop an air breather when the time is right.
The operative statement in the BAA is, "The HSSW Demo program is a risk reduction program for the development of technologies needed for a hypersonic, air-launched cruise missile." solid rocket != cruise missile. Other propulsion systems might apply but I can't see this one being applicable.
DSE said:sferrin said:If it matches the range/speed requirement why not?
I don't see how that could be done with a pure solid rocket, but I'll willing to read any reference you could point to which come close to the range of the notional X-51A. Program wise this appears to more of the first steps of weaponizing X-51A, look at the funding levels.
bobbymike said:sferrin - what is that high speed ram jet/rocket from the 60's or 70's my memory fails me. I read a story that during a test the throttle control malfunctioned and it reached a speed of Mach 5
DSE said:Program delayed until further notice. Sequestration shows its ugly head?

Like what? I hope they're not claiming D-21 experience from half a century ago counts for much.

Jeez!
What turned you into such a cynic?
Yea, I think it counts.

I disagree. Why? Simple: the *people* who developed the D-21 are retired or *dead.* What "experience" can a company claim if all the people involved are no longer involved? Lockheed probably can't even make a valid claim about the data generated during D-21 development... they've probably chucked most of it, and don't know what to do with the rest.
shockonlip said:You may not agree on the legacy aspects Scott. But to me these things matter.
If you are a skunk works engineer, you know about that legacy and that you
are continuing from where these legendary guys left off! From the higher supersonic
realm into the hypersonic one! You have a lot to live up to. And it pushes you
forward! You study harder. Think outside the box better. Work as a team better.
Same with engineers at the other aerospace firms from the past. Or it would with me!

DSE said:Hopefully not. Given budgetary issues, it could be a s simple as a new start can't happen in FY13? Hopefully, we'll see this reissued in FY14?
bobbymike said:No Demo
The Air Force Research Lab's munitions directorate has canceled a technology demonstration for its High Speed Strike Weapon (HSSW) capability and is instead "pursuing an alternate strategy" for updating industry on its research, an Air Force Materiel Command spokeswoman told Inside the Air Force this week. AFRL announced the cancellation on the Federal Business Opportunities website last week. HSSW is being designed as an air-breathing, hypersonic precision round and is intended to improve the effectiveness of fifth-generation aircraft against anti-access, aerial-denial capabilities. Despite the cancellation, HSSW remains a strongly supported program, according to the spokeswoman.

Raytheon Missile Systems designs, develops and produces missile systems for critical requirements. RMS is investing in hypersonic research, aggressively pursuing key technologies required to operate successfully in the hypersonic environment, and meeting stressing requirements.
Raytheon is seeking to hire or contract with key technical experts in thermal, aerodynamic performance, materials, propulsion, airframe and testing methods to assist in conducting this research and execute contract tasking. We will focus on harvesting these critical hypersonic domain technologies for insertion into ongoing hypersonic programs.

The pictures on the display behind are also quite interesting.
