The hypersonic rivalry hots up – great when it materialises

The hypersonic rivalry hots up – great when it materialises

Don’t just laugh. Sure Icarus paid with his life as possibly the first to try to fly and the world that knew laughed.

I sat many times as a very young schoolboy with many other youngsters along with accompanying parents/teachers at the Scientific Research Institute and listened in awe and viewed sketches on paper and a ‘Blackboard’ (what is that you may ask?) and listened to an Englishman talk in depth about space, space travel, rockets, satellites including geo stationary ones and space stations. Yes Peenmunde had been shut at the end of WWII and those scientists that were now safely in the US had continued work on research into rockets, etc.
Yet no space rocket had been fired, no human as yet launched into space and here was Arthur C. Clarke extolling the definite possibilities to us kids and our parents.

Interestingly we did not laugh instead in our respective college labs we tried to understand his teachings/lectures.

Hence this post is about seeing into the future and believing that hypersonic travel is likely to happen. (I hope in my lifetime)

After all people laughed at Concorde, it happened (sadly also gone) and I have met and shaken the hands of many who helped design including the techs (acknowledged as the unsung heroes of the project) who built tiny models in wood (seen many of then at RAE) for traditional wind tunnel testing (no Computer simulation then).

I believe in the work of Reaction Engines and LAPCAT – http://www.reactionengines.co.uk/lapcat.html
“…to reduce long-distance flights, e.g. From Brussels to Sydney, to less than 2 to 4 hours. Achieving this goal intrinsically requires a new flight regime for commercial transport with Mach numbers ranging from 4 to 8.”

Here on Day 1 of the Paris Air Show another project

“Futuristic Zehst primed for 2050 take-off

With a shape that strongly resembles the now defunct Concorde and a promise to reduce journey times between Paris and Tokyo to 2½ hours, the EADS “Zehst” is designed to grab headlines….

The Zehst (zero emission high-speed transport) – a joint project with Japan – will take off using regular turbofan engines before rocket boosters kick in to send the aircraft soaring to a 32km altitude. Standard passenger jets travel at 11km high….

….EADS says all of the necessary technology is available, but an unmanned prototype is unlikely before 2020.

The only shame is that the first commercial flights are not anticipated until 2050 at the earliest.”

I like it – R&D is alive and well and the accounting standards directly concerned with R&D and IP was the title of my recent dissertation.😎

Shame that all the huge expense and possible ‘brain power’ being lost in global terrorism and vengeance (both it’s perpetration and prevention) cannot be instead channelled for the good of humanity.🙁

I also immediately thought of Reaction Engines when I saw that EADS announcement.
I have the feeling that the proposed design with 3 propulsion sources is a `conservative` design, but that they would consider Reaction`s engine if it works and is mature. Carrying redundant propulsion like that has got to carry a performance hit (at first I thought they could eject the turbo-fans to autonomously land via UAV shell, but then realized powered flight is de facto necessary for landing sequence if they want a `civil product` and not a Space Shuttle), and rockets kicking in to get to Mach speed (`ONLY 1.5G accelartion` or something) doesn`t seem quite the standard airliner experince (I believe Reaction can provide more continual acceleration). Reaction seem to be progressing quite nicely, and I suspect will find their way into anything EADS does like this. I actually found the 2050 number to be quite late… At the rate Reaction is progressing, something more like 2040 (almost 30 years from now, after all!) seems quite do-able, and the featured propulsion in ZEHST is less challenging technically than Reaction`s approach.

Also interesting to see British companies (Hypermach + SonicBlue) trying the SSBJ thing, in the Mach 3 range. In all honesty, it seems like a partnership with somebody like Dassault (or another OEM) would be most auspicious, if just for marketing and world-wide support. Interesting to see the engine side of things being tackled, which is what`s really needed for such a project.
