Okay, as promised, here's some more info from

'Fireflies and Other UAVs'.


Model 329 'Spirit' :-

Program commenced in 1985, as a company-sponsored HALE system.

potential missions included comms relay, ELINT, sonobouy monitoring

for ASW, and long range weather monitoring. Growth versions were

envisaged for over-the horizon targeting and cruise missile early

warning and tracking.

Span was to be 85' with an aspect ratio of 30. The fuselage was to be

40' long, depending on payload, and height, 14'.

Cruise altitude was to be 50,000' with a 300lb payload. Gross weight was

to be 4,500lbs, and empty weight 2,500lbs approx.

Time on station was expected to be 80 hours.

Construction was to be primarily of graphite epoxy, with Kevlar in the

wing, and secondary structure of glass fibre.

Construction of the prototype was to be performed by Scaled Composites.

For initial flights the aircraft was to be fitted with a cockpit and piloted,

see below, this later being replaced with a payload.

Propulsion was to be a liquid-cooled six-cylinder Teledyne Continental

engine of 155-160 hp, essentially a six-cylinder version of the Rutan Voyager's

rear engine.

Navigational equipment studied included GPS-updated INS, and TRA's own

system.

Interest was shown in the model 329 by several branches of the Military,

however funding was not forthcoming. Part of the reason for this was

the non-existence of a suitable mission payload, meaning that further funds

would for development of this, in addition to the airframe.

Therefore, development did not proceed.

Star, are these what you need ??    ;D
