Secret Stealth VTOL Transport - "Senior Citizen"
« on: June 21, 2006, 04:18:25 pm »
I have found that murky image in one of zillion AFRL ppt presentations, that serves for me a source of very interesting stuff for several years that proves to be real metall later...like knowledge of what the hell X-41 or X-42 would be three or four years ago.

Needless to say that fan-in-wings VTOL resembles very much 'Northrop Senior Citizen' what-ifs I have seen, but the source is much more serious than one's imagination. Just wanted to share it with you.

From the Internet (link: http://personal.inet.fi/cool/foxfour/black/aircraft.html):

Quote
The codename "Senior Citizen" was originally thought to be associated with the rumoured Aurora reconnaissance plane, but it is now thought to be a stealth V/STOL special forces transport aircraft. Boeing and Northrop probably participated in a DARPA competition in the late 1980s and Boeing's proposal was chosen for development. Funding for the project was ceased in 1993, presumably before the aircraft was ready. However, there are some sighting reports of a large, slow moving double delta winged aircraft. A drawing by an anynomous Boeing employee seems to descriebe this plane and it resembles a published Boeing study for such a vehicle.
Several years ago I had read an article somewhere about some work on a neutral buoyancy aircraft that combined a flying wing planform with helium gas cells- it was supposed to be stealthy and very quiet and combined aspects of airships with aircraft.

That's 1994 information from Skunk Works Digest based on DoD budget documens regarding Senior Citizen

Volume 05 : Number 149
Wednesday, 24 August 1994 (oh, that's pretty old stuff)

Subject: secret SENIOR CITIZEN aircraft revealed!!

There has been a lot of speculation about the secret U.S. Air Force aircraft
code-named SENIOR CITIZEN. Some people have stated that this code-name refers
to a hypersonic SR-71 follow-on ("Aurora") while others have stated that
it refers to the small bat-like Stealth aircraft that Steve Douglass
photographed in New Mexico (sometimes referred to as the "TR-3A"). Based
on a Department of Defense document that I just received, I will reveal
what the SENIOR CITIZEN aircraft really is.

SENIOR CITIZEN is an advanced transport aircraft!!

According to Department of Defense document DoD7045.7-H, "FYDP Program
Structure", October 1993, SENIOR CITIZEN (Program Element 0401316F) is a
tactical airlift aircraft. It might be a STOL (Short Take-off and Landing)
aircraft, because there have been several advanced STOL aircraft funded
under program category 04013xxx.

WOW It seem that I must check this web and Gregorys posts every day  ;D

Some time ago I made drawings of what-if Northrops Senior Citizen tactical fan in wing transport, but they were based mainly on B-2 (to share parts for lower costs). They actually does not correspond at least to wing platform of drawings.

I've read somewhere on the net that Senior Citizen scetch on which Matej made his beautifuk drawings, was made by anonimous Boeing employee...any details of this story? Where first info of tht stuff appeared, does anyone know?

I was under the impression that SENIOR CITIZEN had nothing to do with any of these flying wing concepts, but rather had more to do with a Burt Rutan design...

Who other than Matej knows  :D  There is a problem, because we are talking about two different designs. I made my drawings from scetch that I received from my reliable source in USA. Similar but smaller I later found here: http://members.macconnect.com/users/q/quellish/Other/other.html

Info about "employee cause" can be found in another Skunk Works Digest (v05.n395):

"The picture is of a turbofan powered, low-observable ('Stealth') V/STOL advanced tactical transport design, and is taken from the technical paper "Technology and design considerations for an advanced theater transport", 1990, by Richard Wible, Technology Exploitation Directorate, Wright-Patterson AFB. This may be similar or very close to Program Element 0401316F, SENIOR CITIZEN. In the same GIF is a picture of a Boeing "Advanced Theater Transport" aircraft design, provided by Rick Pavek (kuryakin@arn.net)."

This is the reason why I was so surprised, when you sent me bigger one with name that suggests, that it is not Boeing but Lockheed design.

I think that SOFA will be my next drawing project. Which version should I draw?

I am looking for links hints tips or pointers towards a US Stealthy Transport project. To be used for covert insertion and exfiltration of special forces. Believed to have been based on the Boeing YC-14 http://home.cinci.rr.com/estople/weirdair/yc14.jpg utilising the overwing efflux to mask IR signature and noise from in front and below and to use modified rear engine structure to diffuse hot efflux ala F-117. I think it may have had a project name in the senior series. At one time 6th S.O.S. at Hurlbert Field Florida had a US civilian registered AN-32 N6505 in service. I believe at the same time approx they leased a civilian AN-74/72 to provide test team pilots with hands on experience of flying a Coander effect aircraft, which I understand is unconventional in its handling when flown asymmetrically. I.E. loses lift as well as thrust on the affected side. Some data from the XC-8A project http://history.nasa.gov/SP-3300/f107.jpg may have been used as well.
It is quite possible that the aircraft was not taken into service or production as the V-22 Osprey will now fulfill that role.
Your time and trouble much appreciated,
Be lucky
David
I have tried searching on here without success if I have missed the blindingly obvious, sorry.
They can fly but they can't hide.

Hmmm...may be David is referring to something different? I can't see using Coanda effect anyway being used in 'classic' Senior Citizen impression. Can you at least point at sources that lead you to conclusion of existence of such a project ?
