Tier II Plus UAV competition

Hi,

Orbital Sciences/Westinghouse Tier II HAE UAV

Northrop Grumman, Westinghouse, Scaled Composites, AeroViroment and PAR Government Systems is here:

Loral, Frontier Systems, Fairchild Systems is believed to be W570.

So there are two remaining competitors:

Raytheon, Lockheed, Allied Signal and Teledyne Ryan Aeronautical, E-systems, GDE systems, Adroit systems.


Does anybody have any additonal material. Also - is anybody able to identify this design, that seems to be the Tier II Plus proposal?

E-Systems also paired with Grob on an Egrett variant for Tier II+

Although the Global Hawk and the two Rutan collaborations (Northrop Grumman and Orbital Sciences) are generally known, there were quite a few interesting Tier II+ contenders that sank into oblivion. My favorite is this, from Mission Technologies of Hondo, Texas. According to Flight International 1-7 June 1994, this "twin-wing, twin-boom, twin-engine aircraft would have 24h endurance. With a 28m wingspan, the take-off weight would be 1,600kg".

 

[AeroFranz]

Cool. I had never seen this.
Isn't 1,600 kg a little bit light for this class of vehicle? I mean, the latest Global hawk block 40 carries 1,600 kg of payload.

That is NG/Scaled's design.
Found this today, which should be of extreme interest to anyone on this thread:
http://www.nps.edu/Academics/Institutes/Meyer/docs/A%20study%20of%20reconnaissance%20surveillance%20UAV.pdf

3views of each design on pg 31

 

[Stargazer2006]

Awesome find, by all means!!!
Thank you so much!

 

[AeroFranz]

quellish, that's a GREAT document. Thanks for sharing

 

[quellish]

quellish, that's a GREAT document. Thanks for sharing

The NG flying wing model is pretty cool I wish the 3 views were a little more detailed for the modelers, but you take what you can get.

 

[overscan (PaulMM)]

From PDF...

Matej's design above is similar to the Northrop Grumman proposal.

[hesham]

Excellent my dear Overscan,thank you very much.

 

[Stargazer2006]

What a great weekend this has been on the forum! Thanks for sharing these Overscan.
Do you confirm that these photos all depict Northrop Grumman proposals? The one at the bottom is very different from the rest.

 

[Matej]

They are the extract from the PDF document - just click the link and take a look.

Oops... I'd stopped halfway through the document (too much to read already!). Wow!

one of the greatest finds for the story of forum, thanks!

 

[Madurai]

That Northrop-Grumman proposal... Does it remind anyone else of the YA-9?

 

[Matej]

Matej's design above is similar to the Northrop Grumman proposal.

Similar but not exact. Now I can identify my first image as the IAI HA-13 - early Tier II+ proposal.

 

[Stargazer2006]

That Northrop-Grumman proposal... Does it remind anyone else of the YA-9?

Certainly did with me too!

 

[Mike OTDP]

The sketch of the Loral bid doesn't show the radomes...a big one on the top and the bottom. Roughly tripled the thickness of the fuselage at that point.

 

[Matej]

There are other significant differencies. For example original W570A had straight trailing edge (only with the end of the wing in angle), while this proposal has the sawtooth.

Somewhat on topic: Page 10 has a comparison of real world use of the U-2 vs GlobalHawk

[Stargazer2006]

Tier II+ proposals from Northrop Grumman, Orbital Sciences and... Martin.

All with Burt Rutan/Scaled at the design helm... ;D

 

[AeroFranz]

Nice compilation Stephane!


the second picture shows a tail configuration that would later resurface on the Firebird, with the distinctive canted vertical fins.

[Stargazer2006]

Thanks a lot, flateric! Didn't realize the Martin Marietta design had ever been published at the time...

One thing I find interesting is this sentence: "Additionally, one of the designs is a B-2 lookalike".
Since we haven't seen the Loral entry, and since Loral is known to have produced a flying wing UAV later on, can we see this as an indication that the "B-2 lookalike" might be the Loral proposal? Just a thought.
