I'll believe it when they finish certifying it.

In regards to your question CF, my guess would be cost. Perhaps after several design iterations the team found this to be the most cost-effective solution. I certainly cannot imagine an integrated turbine/ramjet being economically viable right now for even a high-end business jet, and the engine itself would have to come from one of the dominant manufacturers to convince operators that it can be serviced and maintained in a timely fashion. Rich people/charter operators aren't about to blow several mil on a bizjet that only looks good on the tarmac but is insanely expensive to operate and difficult to get parts for.

Rather than reinventing the wheel, it was most likely "easier" to combine existing technologies into a single airframe. My question would be - How do they replenish the rockets after each flight, or would it be made to run on the same fuel as the ramjet or turbine engine?

That's interesting, I always thought "zero emission" means, well, you don't burn any fuel so there is no emission
if the fuel comes from plants which have absorbed CO2, the emission will be neutralised by this, and the end result is said to be zero as well

bullshit if you ask me...

Nonetheless, in 40-50 years time (unmanned demonstrator by 2020 + 30-40 years to get the real deal) I don't think there will be any need for this because holoprojection or beaming or something else will be that advanced that you a) don't need to be on site or b) you will get there much quicker.
And on April 5, 2063 we'll start FTL spaceflight. I'll be well into my 80s then, but I'll be there.

I don't like how they 'intend' to use rockets. Why not use a bypass type engine like the sr-71? I'm looking at you nsx_23.
My guess? They need the booster rocket to make the step between the operating speed ranges of the high bypass ratio turbofans used for takeoff and the ramjet used at high altitude.

A combined engine like what was used on the SR71 would be too noisy/fuel consuming when in turbofan mode for commercial operation.

I think that if this program does get off the ground, it will be more successful than concorde. Concorde was only a little over 2x faster than standard passenger jets and while a 10 hour flight becoming a 5 hour flight is significant, It's still a 5-7 hour trip, which means it's just a little bit to slow to just pop over to another continent during business hours. Flying 4x faster makes that 10 hour flight a 2.5 hour flight and suddenly you're just a long car trip away from LA to London. If it flew at mach 5 I think it would be even more likely to be successful.

Yes, as in the airport.

On the way home from the beach, we swung by the Evergreen Aviation & Space Museum. We were in a hurry so we only drove through the parking lot, but still saw some nice birds.























Spruce Goose and it's 8 engines peaking out:







Yes, this is a 747 on the roof of a building that is being used as a water slide start point. They flew it in and then lifted it up.

An era of unprecedented travel times linking New York to Paris in under 2h and New York to Sydney in 5h could become reality within the next decade, says supersonic business jet developer HyperMach Europe.

At the show this morning the UK-headquartered company (hall 4, stand B172) unveiled its 20-seat SonicStar concept, which it says is designed to fly at Mach 3.5 with no sonic boom overland.

?We will fly at twice the speed of Concorde, so that the other side of the world feels like it?s just down the road,? said Richard Lugg, Hypermach chief executive and chief scientist.

Lugg ? a military aircraft designer, engineer and self-confessed Concorde enthusiast ? said HyperMach is driven by a mission to change air transport. ?With an eye to the future, but feet firmly rooted in solid scientific research, the development of SonicStar makes what was previously impossible ? reality.?

The SonicStar?s 54,700lb-thrust (245kN) class S-Magjet 4000X propulsion system has been under development for six years. It is at least 30% more fuel efficient than the Rolls-Royce Olympus 593 engine that powered Concorde, said Lugg, and gives a 20% higher thrust-to-weight ratio. ?This will be the first hybrid engine to offer a highly efficient, supersonic, variable bypass fan ratio engine design,? he added.

The engine operates electrically by generating large quantities of onboard electric power through its superconducting turbine ring generator technology. Power generation and thrust comes from the five-stage, superconducting axial turbine that allows the SonicStar to reach a height of 62,000ft (18,900m) at M3.5.

The engine will be developed in the UK by sister company SonicBlue, with an unnamed manufacturing partner and with the support of the UK government. HyperMach is also holding discussions with other potential manufacturing and funding partners to help bring the aircraft to market.

First flight of the SonicStar is set for June 2021, but Lugg would not be drawn on a certification timeframe. The market for the $80 million-plus aircraft is ?in the thousands?, he added, with demand expected to come from the VVIP travel and cargo sectors.

Maybe I will get to Australia someday after all. I am a bit claustrophobic and could not do it on a traditional flight.

Man, that looks like such an awesome museum. Definitely would like to go there some day!
Yeah, it's a good museum. All the good stuff is inside though. There's a SR-71 for example parked under the wing of the Spruce Goose.

The Convair F-102 Delta Dagger is the aircraft closes to the camera. The aircraft in the background is a Convair F-106 Delta Dart.

No topic on Le Bourget air show yet?

I will not attend this year Le Bourget air show , so i search trough french forums for some links of pics or streaming.

First , the 20th june a big mistake by ground crew on taxyways cost the Airbus A380 a good chunk of its right wing.



Link to a page of pics https://picasaweb.google.com/115364235018659855589/LeBourget


Streaming live :

another video link : http://bcove.me/7lk6xuf1


If i found something else , i will post it later.

Fuck yeah, Beriev. Said this many times, but I love this thing. It may not exactly be the the model of efficiency but damn it looks amazing.
