Concorde Mark 2: Airbus files plans for new supersonic jet

New jet could cut flight time from London to New York to just one hour

The new jet could fly from London to New York in an hour - opening up the possibility of a transatlantic return journey in a day.

Concorde 2 would be capable of flying more than four times the speed of sound – or more than 2,500mph, according to documents lodged with the US Patent Office by the aerospace and defence group

The filings refer to an “ultra-rapid air vehicle” and “method of aerial locomotion” for the aircraft, which would cruise at an altitude of more than 100,000ft and carry up to 20 passengers or two or three tons of cargo for distances of about 5,500 miles.

According to the patent, power would come from three different types of engines:

• “at least one” conventional jet that could be retracted into the fuselage

• one or more ramjets, which use the forward speed of the aircraft to compress the air entering them before it is mixed with fuel and ignited

• a rocket motor powered by hydrogen and oxygen.

Flights in the new aircraft look set to be a wild ride, with the rocket motor used in combination with conventional jets to power a “near vertical ascendant flight” until its breaks the sound barrier when the engines are retracted in the fuselage and the ramjets take over.

According to Ben Rich (author of the book I am quoting) the Air conditioner fed air into the cockpit at -40 degrees. In spite of that the thing was an oven.

The XB 70 was shirt sleeve comfort at Mach 3.0. Aerodynamic heating increases at the square of the increase in speed. So Mach 4 should be good for furnace brazing in the cockpit....

mach 4.5 = 1 531.305 m / s...............so maybe they could outrun the heat!.................B^)

Ben Rich tells a story about a discussion of the Aurora, the mythical Mach 6 replacement for the Blackbird. He told the guy they were heat warping Titanium with the blackbird. That shut the guy up.

Iridium has the highest melting point. 4800 f I think. But a bit heavy for aircraft.

Yikes. . .I think many share that opinion.

Cockpit temp? Better check that as the dash-board instruments (standard analog) would have warped and stopped functioning.

The jet glowed from the heat but the cockpit was pressurized and air conditioned and the pilot and WSO wore space-suite in case of decompression. . .wouldn't do to lose pressure and be sitting there in nothing but your green nomex flight suite.

Flying above 50,00 feet today requires you wear the space-suite. . .regulations. . .not saying I EVER went above 50K, not saying that, but it is a spectacular view from up there. . .

Above 50,000 feet not an issue as the pressure wave dissipates well before hitting the ground. Sub-sonic flight required over land, not over the ocean. Now, I've flown mach over the water at 5,000 feet, no issues, fun. Flown mach over land, too, and much lower in areas where there is no speed restriction. . .fun to watch the shock-wave ‘puff’ over ponds. . .
