Mole said:There must be hundreds of these, so open the floodgates, who has sketches and pics of unbuilt designs by Burt Rutan, whether back in his Rutan Aircraft Factory days or at Scaled Composites?
Stargazer2006 said:Hi! I'm Stephen and I'm the webmaster of the Stargazer website you mentioned above.
I am honored that you quoted my work and find it a valuable source, and happy you found interesting stuff there!
In return, I want to thank Orionblamblam for the scans of the Rutan Commuter... I'd been searching for this for ages!!!

Just found this, which I think sheds some big light on what the Maliboo project was:
"At that meeting, C.C., Burt and I sketched a vary large, liquid-powered air launched manned booster system (the rocket was code-named "Maliboo", the carrier aircraft "Grasshopper"; Max and C.C. designed the spacecraft, a small, two-seat winged thing). Burt wanted to put rocket engines on the carrier aircraft to increase its flight path angle and avoid a wing in the rocket. I wanted a wing on the rocket and no rocket engines on the aircraft. A substantially modified 1/4 to 1/3 scale version of Grasshopper flew many years later under the name "White Knight"."

First flown in 2010, Firebird is not the first UAV Scaled has designed for Northrop. Back in 2004, Rutan's outfit produced two concepts for the company, for the US Air Force's then-emerging Hunter-Killer requirement. The Model 395 was an unmanned derivative of Scaled's Proteus high-altitude research aircraft; the Model 396 was a scaled-down Global Hawk. In the end, Hunter-Killer become the MQ-9 Reaper and the rest is history.
AeroFranz said:All I think of offer is a high-altitude UAV research airplane built in collaboration with NASA. It would have featured a short central boom with a tractor prop engine featuring triple(?) turbocharging, a medium aspect ratio untapered wing, and outboard short booms carrying outboard horizontal stabilizers. A friend has a framed picture in his office.
Just call me Ray said:Three-stage turbocharging, or I guess even simpler terms, it has three turbochargers (so the air gets compressed three times)
Hobbes said:Three-stage turbocharging seems kind of unlikely. Two-stage turbocharging can get you at least 10 bar of overpressure which is way more than you need. Adding another stage just complicates the plumbing for no apparent gain.
