Lockheed L-2000 Mockup

hi-rez, jetliner, Patreon, transports 1 Response »

Sep 252018

The Lockheed L-2000 was a Mach 3 SST designed to compete against the Boeing 2707 in the mid 1960’s. It was an elegant and classy looking design, but was passed over by the US Government in favor of the Boeing design. Lockheed built a full scale and reasonably convincing mockup of the craft, using it for both study and PR purposes.

The L-2000 looked like nothing quite so much as a cross between the Concorde and the SR-71.

It has been *years* since I have released any “Air & Space Drawings & Documents,” high rez scans of vintage aerospace items. At last, I’m adding new items. The complete catalog can be seen HERE.

New items. Each are available for $4.

Air Document 27: “Design Study for an Air Force Model F-82E Airplane Modified to a Ground Attack Airplane” A 24-page study from 1949 for a twin-bodied F-82 modified with Allison turboprop engines. The engines would be mounted in the mid-fuselage, about where the cockpits originally were; the cockpits would be moved forward to compensate. The document, taken from a vintage copy printed from microfilm, includes numerous diagrams and B&W art.

Air Document 28: “This Is The Life With Lockheed” A 36-page booklet produced by Lockheed, Georgia Division, showing the wonders of working there in 1959. Includes not only descriptions and photos of the local environment and amenities but also photos of Lockheed facilities, products and projects. An interesting view of a very different era.

Air Document 29: “SAM-D Air Defense Weapon System” A 1973 Redstone Arsenal information booklet on the Surface-to-Air Missile, Development, which became the “Patriot” anti-aircraft/ anti-missile missile. The booklet describes the various elements of a SAM-D deployment.

Air Document 30: “V-397 (Regulus II) Summary Report” A 42-page 1955 Chance-Vought report on the Regulus II supersonic cruise missile. Includes data and glorious diagrams on the tactical missile as well as the flight test vehicle with landing gear. Scanned from a vintage printout from microfilm.

Air Document 31: “Republic XF-103 data” Dating from the mid-50’s, this collection of data and diagrams of the Mach 3+ XF-103 interceptor comes not from Republic, but from Lockheed. A rare look into corporate “competition data gathering,” this 21-page data file shows the sort of information that Lockheed put together on the designs put forward by their competitors.

Several of these were released *four* *years* ago to patrons of the Aerospace Projects Review Patreon. Patrons receive items such as these at a low cost and years earlier than waiting for them to appear on the Drawing & documents catalog… and most of the Patreon items *won’t* appear here.

Bell D-270-900-100 Tiltrotor

Sep 052018

A 1969 Bell Helicopter design for a high speed stowed-rotor tiltrotor. This was meant for USAF search and rescue and featured gun turrets fore and aft (each with a Minigun) and four turboshaft engines under the wings. Doubtless the gearing from the engines up through the pylons and along the wings to the nacelles would have been an engineering nightmare. But if it worked, it would have resulted in a tiltrotor with the hover performance of the V-22 and a cruise speed of 400 knots.

An article on the similar D270-900-112 (the main visual difference being that the engines were separately podded) was included in US VTOL Projects #1.

I have made the much-larger full-rez scan of the cutaway available to $10+ APR Patreon patrons. If this sort of thing is of interest, please consider signing up for the APR Patreon.

Rotating space station art

An artists concept of a rotating space station circa 1962. It has a NASA ID number but it *may* be North American Aviation, as they designed a space station essentially identical to this, as described and illustrated in an article written by Dennis R. Jenkins for Aerospace Projects Review issue V1N6. This space station was designed to be launched as a single payload atop a two-stage Saturn V; it would unfold once in orbit to form the pseudo-toroidal shape. This piece of art depicts a central docking hub that must have been intended to be rotationally decoupled from the station. The space station must have been non-rotating at the point in time illustrated, or those spacewalking astronauts are going to have an interesting time doing their job.

A high-rez scan of this piece of art has been uploaded to the 2018-08 APR Extras folder on Dropbox for APR Patreon patrons at the $4 level and above. If this sort of thing is of interest, please consider signing up for the APR Patreon.

XP-55 Ascender Cutaway

Aug 142018

The Curtiss-Wright XP-55 Ascender was a tailless fighter design from WWII. It was intended to be an improvement on then-current designs in terms of performance, but proved to be disappointing. After years of development and flight testing, it was overtaken by jet propulsion and failed to make it into production.

I have made the much-larger full-rez scan of the cutaway available to $10+ APR Patreon patrons. If this sort of thing is of interest, please consider signing up for the APR Patreon.

Bell fold-back tiltrotor

Aug 122018

A photo of a 1960’s Bell Helicopter concept for a high-speed tiltrotor. In this design the aircraft would operate in hover and low speed much like the V-22, but at higher speeds the prop-rotors would stop rotating and fold back to reduce drag. Forward thrust would be provided by pure jet exhaust from the convertible turboshaft engines within the fuselage.

I have uploaded high-rez scans of the color glossy photo to the 2018-08 APR Extras folder on Dropbox for APR Patrons at the $4 level and up.

“Life With Lockheed”

Jun 302018

In 1959 Lockheed printed up a self-promotion booklet to sell to new and prospective employees the advantages of their Georgia facility. It includes a lot of photos showing the joys of working in the deep south in the era before universal adoption of air conditioning while wearing three piece suits and ties, as well as photos and art of the various facilities, aircraft and projects then at work at Lockheed-Georgia.

I have posted the full-rez scan of the booklet, available to $10+ APR Patreon patrons. If this sort of thing is of interest, please consider signing up for the APR Patreon.

Reusable Atlas model photos

May 182018

In the 1960’s, prior to the Space Shuttle program, General Dynamics/Convair studied using the Atlas ICBM as a space launch system. no surprise there. But one concept called for a nearly fully reusable Atlas, equipped with wings, jet engines, landing gear and a cockpit to recover the booster in one reusable piece. It would be topped with either an expendable Centaur and satellite/space probe upper stage or a smallish manned lifting body spaceplane with its own built-in propulsive capability. At the time General Dynamics released sizable “educational” cards with information and photos of models of the reusable Atlas. Unlike the normal Atlas, this version did not drop the outboard “booster’ engines, but kept them throughout the mission. An inflatable, deployable afterbody was proposed to fair over the engines after burnout to reduce base drag.

I have uploaded righ-rez scans of both sides of this poster-sized card to the 2018-05 APR Extras folder on Dropbox for APR Patrons at the $4 level and up.

Additionally, a report on this concept is available as Space Doc 52.
