Space Projects / Re: Skylon Spaceplane
« Last post by FighterJock on Today at 04:03:34 am »
This has been covered upthread, but giving it a bump.

BAE Systems has invested in Reaction Engines and has developed concept of a hypersonic strike aircraft that uses SABRE. The notable thing about the design is that it separates the intake and rocket components and bypasses the problem of the hot plume damaging the sides of the vehicle. It is an aircraft and not a spaceplane - but Reaction Engines is called Reaction Engines and not Skylon Corp because they acknowledge that they don't have the capital to develop a complete spaceplane, but have a propulsion concept that is applicable to a spaceplane among other things. The AFRL also has an interest in the engine for the first stage of a 2STO system.

First time that I have seen this design, looks like a similar concept to the Skunk Works SR-72.

Perhaps a bit off topic but does anyone have a single image of an Egyptian Patriot battery component?

Or a news article mentioning either delivery of Patriot to Egypt or cancellation of the 1999 agreement?

Early Aircraft Projects / Re: Handley Page HP 47

"The Handley Page H.P.47 was a British single-engined low-wing monoplane built to an Air Ministry specification for a general-purpose bomber and torpedo bomber aircraft. Only one was built."

"Behind the radial Bristol Pegasus IM3 engine, producing 650 hp (485 kW) and enclosed in a Townend ring, the semi-monocoque, corrugated skinned fuselage grew in diameter to the pilot's midwing cockpit then remaining constant rearwards to the gunner's position. He sat facing rearwards below the upper fuselage line and out of the slipstream, at a point where the fuselage stepped to a slim and narrowing oval boom. There was usable space inside the fuselage between the cockpits, enough to carry three passengers or two stretcher cases. All the tail surfaces moved; the fin, mounted ahead of the tailplane, moved with the horn-balanced rudder but through smaller angles, changing the camber, and the tailplane and single elevator were similarly coupled. "

Guns: 1 0.303 in (7.7 mm) Vickers machine gun fixed forward firing and 1 0.303 in Lewis machine gun on high speed mounting in rear cockpit"

Picture source
Bottom picture explanation.
"The unusual tail arrangement of the H.P.47 is well shown in these photographs. As the fin and rudder are ahead of the horizontal tail surfaces they are not "blanketed" at large angles of incidence. The picture on the right gives a good idea of the view and field of fire obtained by the rear gunner. "
