Bloodhound to Run 1000 mph

Except this is no dog, this is a car.  The Brits who officially broke the sound barrier on wheels 12 years ago are back with a project to go 1,000 mph in South Africa.  The SSC Thrust hit 763 mph for an average using two jet fighter engines but that isn’t enough now that others want to break the record.  With a hybrid rocket motor this project is aimed at more than setting an amazing record.  They are hoping the involvement of schools and universities will have an effect like the Apollo moon shots did back in the 1960’s by bringing in more students into science degrees.

Quote of the article:

Put it this way, if you fired what used to be the most powerful handgun in the world, Dirty Harry's .44 Magnum, at the tail of the rocket/jet car as it passed and Green toggled the 20,500lb thrust hybrid rocket as the revolver went off, the bullet would never hit the car.

I wonder how big a speeding ticket he’d get for that?

But seriously, I’m skeptical they can do it because the low level speed record for an aircraft is only 994 mph.  An aircraft has a lot less friction to deal with -- not only involving air but with no energy being lost to contact with the ground. The other thing worrying is the dual engine concept with a jet engine and a hybrid rocket motor.  That won’t be the easiest thing to work out. It reminds me of Chuck Yeager’s flight in a similarly augmented NF-104A Starfighter that ended in a crash so vividly depicted in The Right Stuff.

Speaking of Starfighters, I’m looking forward to seeing if the North American Eagle team can break 800 mph with an adapted F-104 Starfighter fuselage on wheels. Being very fond of the F-104 in all its incarnations, I’m rooting for their success.  They’ve been ramping up test runs and have run into some problems lately but it doesn’t look project threatening.

Most people don’t know of it, but back in 1979 Stan Barret broke the sound barrier in the Budweiser Rocket Car built by Hal Needham’s team.  Sadly, the first supersonic car run couldn’t be recognized because it had three wheels and only did a one way trip.   Check out the story at YouTube:

A Very Cool Little Fighter

This a flight demo by a Hungarian pilot flying a JAS39C Gripen at RIAT earlier this year.  Great video of a terrific little plane that Sweden builds for multirole combat. 

 

I think it is the prettiest of the “Eurocanards” flying and fills a critical  need in size and capability.  Many countries can’t afford even medium sized fighters, instead flying smaller ones such as the F-5 Tiger and MiG-21 Fishbed.  A modern replacement for them has been needed for some time. This is what the F-20 aspired to be in the 1980’s and I believe the Saab Gripen is the realization of the dream of a  modern light weight fighter.

The only other competitor is the Chinese/Pakistani JF-17 which I highly doubt is as good a plane, being a radical derivative of the MiG-21. It says much that the Pakistani’s are now buying the larger and more modern J-10 from China instead of more JF-17’s.  Meanwhile, India’s LCA project is still far from service and already out of date.

Interestingly, the Gripen often ends up competing for contracts against bigger fighters such as the F-16C Fighting Falcon, F/A-18E Super Hornet, and France’s Rafale. Currently it is in service with Sweden, Hungary, the Czech Republic, and South Africa.

A new version with a more powerful GE-414 engine, AESA radar, more fuel, and redesigned landing gear is flying in prototype. The Gripen NG promises greater range and weapons load along with better avionics.

Is a New Concorde Needed?

Ran into this photo gallery at the Telegraph depicting renderings of a proposed super sonic transport (SST) being developed by Supersonic Aerospace International.  It is a pretty bird aimed at the business class traveler, essentially a Mach 1.6 private jet that is quiet enough to be used at more airports than the old Concorde SST.  Given the immense costs of fuel used to fly any "super cruise" plane, I don't see a valid market for it during hard economic times.  Sure there are some sheiks out there who would love such a toy, but even they have felt the pinch the last year. Unless there is a huge turnaround in the global economy in the next decade, the timing of the aircraft will be poor.

Interestingly, Lockheed's Skunkworks designed the 'QSST', or Quiet SST, plane. The lack of afterburners should reduce takeoff noise considerably, but the F-22A Raptor pilots have found that it is more economical to use afterburners to reach supersonic speeds and then throttle back to cruise.  It will require a lot more fuel pushing through the so called "sound barrier" of denser air from what they've said.

It would make a great model kit though, look at those lines!
