You probably don't need us to tell you that Mach 9 is ludicrously fast. The fastest manned airplane in history remains the Lockheed SR-71 Blackbird, with a top speed of over Mach 3 — and that was only designed to carry two pilots. Venus Aerospace wants its plane to ferry a dozen passengers, plus crew.
So a closer touchstone would be the legendary Concorde supersonic airliner, which boasted a top speed of around Mach 2 and an impressive capacity of over 100 hundred passengers. Still, going from twice the speed of sound to nine times the speed of sound would be quite the leap for a passenger plane. Unlike those icons of aerial speed, though, the Dugglebys want their plane, which they're calling "Stargazer," to make use of rocket engines that will bump the craft with a ten minute speed boost after take off, propelling it to over 30 miles in altitude. For comparison, the typical cruising altitude of commercial airliners is between six to eight miles.
That would obviously entail a powerful rocket, but building something powerful is the easy part. Efficiency is the real challenge, as rocket engines aren't nearly as economical as their air-breathing jet engine counterparts. In rocket time, an all-out ten minute burn is an eternity.
An RDRE, on the other hand, creates a continuing series of controlled detonations around a circular, or annular, channel. Designing such an engine isn’t easy, but the payoff is worth it, producing more thrust with less fuel.notes that tests have generally found RDEs to be about ten percent more fuel efficient than conventional rockets — an increase that's small percentage-wise, but big in terms of practical impact.
4 hours to the airport, 2 hours pre-boarding 1 hour flight Same again the other end. 13 hours
Changes everything but flight would have to be cheap.wich I doubt,rocket fuel?
Interesting, and how is it powered ?
Hugely - spend a weekend in Australia from the UK - WOW !! I just hope that the costs of a flight will be cheap enough for me to take advantage before I die. Bring it on !! 👏
Only if they don’t produce sonic booms.
