Phantom Works' Yaw Thrust Vectoring (X-36, X-45)

[donnage99]

Here to discuss what the title said. Anyone got any information (some closed up pix on the nozzles would be greatly appreciated). This is the only thing I found:

hesham posted this NASA report in the Boeing JAST/JSF/X-32 projects thread which shows concepts with yaw thrust vectoring nozzles that look a little like a Harrier/Pegasus nozzle mounted horizontally.

Hi,

the Boeing Model-988.

Looking at donnage99's post the nozzle doesn't look deep enough to be like the concepts in hesham's post. Definitely looks like something rotates in there though ???

Now that is interesting....

Was there ever a tailless aircraft that actually demonstrated controllability and maneuverability at supersonic speeds?

And to stay on topic, here is one of Phantom Works recent NGAD concept art...

There are some edited shots of the X-31 with its tail removed. This never happened but the flight control software war modified to fly with the ruder disabled, they took it up to mach 1.2. I believe something similar was done with the F-15 active. If the X-44 manta had ever gone ahead we would know a lot more.

Yup. The simulated test of X-31 was called "quasi-tailless"; they've emulated the flight control in such way that they've put the aircraft in a pseudo-tailless flight regime and control under such conditions. Obviously still not a tailless aircraft.
