Do you think scram jet travel will succeed?

Recently, the scram jet was successfully tested. It led to speculation in the press of hypersonic air travel in the future.

However, if we are to remember, this will not be the first time supersonic air travel takes place. As early as the 60s, the concorde was flying supersonic carrying passengers between the UK and France. Unfortunately, it never got widely accepted in the world as a result of the sonic boom it creates as it flies past.

Under such circumstances, do you think a hypersonic air plane carrying passengers will ever succeed in becoming the new passenger aircraft of the future? Do you think such an aircraft will ever replace the conventional passenger aircraft now used?

Dead as a door nail

The technology has been here for almost 50 years and has not been used because it is fundamentally a bad idea.

We were testing scramjets at Marquardt in the 1950's and the technoliogy worked.

Regular ramjets - with subsonic combustion - flew at mach 4 and altitudes over 100k feet on the Lockheed x7.

Scramjets worked in the wind tunnel.

Not used why? Expensive and has no advantage. The Boeing BOMARC - Mach 2.5 interceptor - lost out to the nike because, the Nike did the job cheaper.

I rode on the concorde once - nice but I would never have taken it if someone else were not buying my ticket. And the concorde was slow compared woith these things.

While I'm at it, the LACE Liquid Air Cycle Engine is just as dead. Idea - runway to space airplane. I built a demo functioning small scale model of the LACE. Same deal - too complicated.

Just when you thought the Concorde and super sonic airliner flight was all but dead now the Japanese want to build the ultimate in Super Sonic Airliners to go from Tokyo to Los Angeles or New York in record time and at record speeds. But they need a little help from NASA to do it. Luckily we are certainly learning a lot about the subject and the aviation industry has learned a lot from the Concorde as well. Some of these lessons have not come so cheap and have cost many lives indeed.

The Japanese Space Agency will work with the National Aeronautics and Space Agency to build a new super fast airliner capable of making the trip across the Pacific Ocean in under 3 hours. But how could that be possible? Well using the newest in technology of course and they want to be able to do 5.5 Mach or five and a half times the speed of sound. This is a long-term project and should be done by 2025. How can anything go that fast you ask? Well using a Scram Jet engine which could allow it to go ten times that of a normal commercial jet airliner of today.

This will be a joint project with NASA and Boeing Technologies in a venture with Mitsubishi, Kawasaki, Fuji and Ishikawajima-Harima Heavy Industries said the Japanese Space agency. Excellent indeed and the need for speed is enough to fund the entire project from seed to weed. Consider all this in 2006.
