A piece of artwork from North American illustrating a vertical takeoff and landing aircraft. This was clearly intended for high speed… not only does it have four turbojet engines for forward thrust, if also have variable sweep wings. The complexity here is that the wings have embedded lift fans, probably driven be high pressure exhaust gas from two or more of the main turbojets. The ductwork would be impressive.

Role is unclear, but it appears to be a fighter or strike-fighter. Indications of weapons bays on the fuselage underside; at least one forward-firing gun. No other data available.

Does it looked like it had 4 jet engine? on top of the 6 fans on the wing. Holy crap, this is like some engineers wet dream… with internal weapon storage, I don’t think it have much from for fuel. It took the Indian 20 years to field their jet, this one can easily takes 30 years to develop.

On the aft end of the top one you can see 4 engine nozzles all lit up. How you’re supposed to go about feeding four turbojets with one inlet on the top is beyond me. It also doesn’t help that the location of the intake indicates that the 4 engines will be subject to a lot of engine face flow distortion and total pressure losses.

Variable Sweep and gas-driven lift fans? I would hate to have to design those hinges; presumably whatever they came up with weighed a significant amount.

I think the setting of the scene is a good indicator. I’ve encountered in a few books the worry some Cold War AirLand Battle planners had over the Reds knocking out runways in preemptive strikes. Clearly a VTOL would not be limited by a runway that has suddenly acquired a few new 25 meter wide pot holes. This seems a tad bit more sensible than the other plans to overcome this problem I’ve seen, such as the rocket powered area effect sled that would simply fly the aircraft over the gaps until it reached take off speed.

Charles Ramsey, who helped free Cleveland kidnap victims, gets burgers for life See, now that’s something I can get behind. A guy does the decent thing, and local businesses decide, of their own accord, to provide him with some goodies to thank him. Now hopefully the same restaurants will also provide free burgers for life […]
Grumman Design 619 Art: 3 May 23, 2013
Grumman 619 orbiter coming in for a powered (turbojet) landing. Note the white underside… it is very unlikely that the underside would actually be painted white (much less that it would survive re-entry); instead, this is almost certainly artistic license. […]

Grumman Design 619 Art: 2 May 22, 2013
The Grumman 619 in orbit, deploying a satellite. Here you can see the humped cargo bay doors. Not visible here are turbojets in the cargo bay; they were left out of this particular mission. The orbiter would thus have to land as a pure glider. […]
Woo! May 22, 2013
Tonight I happened across a binder that I haven’t seen in many years, containing a number of reports that I had considered lost. Some of this is in dire need of being written about. But as a teaser and a test, here’s one line from a presentation chart from 1963. Who can say what this […]

Grumman Design 619 Art May 21, 2013
An illustration of Grumman’s 619 Space Shuttle – the final competitor for the competition that North American Rockwell won – lifting off. This design from 1972 was laid out pretty much as the final Space Transportation System was, but with some notable differences: 1) Stabilizing fins on the external tank 2) A “humped” back 3) […]
Oklahoma May 20, 2013
Oklahoma is currently getting trashed by very, very large tornadoes (two miles wide). It’s an ongoing disaster, so if you are in the area, find a hole, dive in and pull it in after you. Most of the time, reporters covering such stories are entirely too gleeful over the mayhem they get to cover. But […]
