XB-26H 44-68221 "Middle River Stump Jumper"

-

     While researching the Martin XB-48 at the National Archives I came across a beautiful set of photos of the XB-26H. Being a Marauder fan, I had to take the time to scan these images for my personal enjoyment. I also thought it would be fun to share this find with people of similar interest.

     TB-26G 44-68221 was modified with tandem main wheels and outriggers in the engine nacelles to support testing of this landing gear configuration. Other changes to the aircraft included external stiffeners on the fuselage to support the additional loads on the airframe. 

      Having the main wheels retract into the fuselage with minimal outriggers for stability allowed potential jet aircraft to have thinner airfoils by placing all that bulk into the fuselage rather than having to have thick wings.

       A stablemate, the Martin XB-48 benefited from the research by using a similar landing gear configuration as well as the XB-47, XB-51 and to an extent the XB-52. 

      In looking at the different pictures you see that the aircraft sits at almost a nose high take off stance rather than the more level ground stance of the B-26. I wonder if this was due to the location of the main wheels in relationship to the center of gravity/lift or normal rotation of a B-26?

     Not sure where the "Stump Jumper" came from in the name, the Middle River was taken from the airfield that the Martin plant was located on. 

      Hopefully these images were as interesting to you and they were to me. I have some detail shots of the landing gear if there is any interest in seeing them.

Howard DBA NASA Aircraft

-
Image
     Here is a design that is seldom mentioned the Howard DBA. The photos come from low speed wind tunnel at Vought. The photo sleeve has Howard Aero written on it and typical of the LSWT photo sleeves does not reveal a model or make for the design. Nor is there a date for the project. It also appears that the test report and the negatives are separated.       This was a design from Howard Aero of San Antonio Texas the same fine folks that created the Howard 500 version of Lockheed's Ventura bomber to meet NASA's need for rocket component transportation. Howard Aero   (VAHF Collection)      The aircraft features 10 engines and two sets of wings along the bulbous fuselage. It also appears to have large clam-shell doors on the front below the cockpit area. Howard Aero   (VAHF Collection)      A model and the LSWT report are on display at USTA.

VF-213 F-14D 164602 Color To The End

2006 saw the last of the F-14D Tomcat fighters leave US Navy fleet service. VF-31 and VF-213 were the last two squadrons to deploy with the F-14. The VF-213 Black Lions painted F-14D 164602 AJ-213, in full colors for the retirement. I had the good fortune to see F-14D 164602 two days after arrival and prior to spraylat being applied for it's storage in AMARG in 2006.  With the exception of the AMARG inventory number ANIK0195, and the yellow 7 indicating an accountable inventory inspection has been completed, the aircraft's markings are untouched.  Some preliminary work to start covering openings has been completed.  Twin tailed Lion that evolved with the squadrons transition from the F-4J Phantom II to the F-14A Tomcat.  AMARG technicians added blocks to the top of each rudder to keep the surfaces from blowing back and forth in the wind potentially damaging hinges and actuators. Foil paper and tape have been used to cover the engin

Lockheed Altair 8D (Y1C-23)

342FH-3B26914-Y1C-23-32-232-Left-Side The Lockheed Altair just captures that late 1920's early 1930's era of aircraft design. The rounded curves of the tail surfaces and the big NACA  engine cowling top off the look. If the landing gear was fixed it would have big rounded wheel spats to accent the design. 342FH-3B26913-Y1C-23-32-232-Left-Front-Langley-Field-19340131 342FH-3B26915-Y1C-23-32-232-Left-Front  The aircraft was powered by the Pratt & Whitney R-1340 Wasp that had a production run of over 34,000 engines that powered many contemporary aircraft including the Chance Vought O2U and O3U Corsairs and the Boeing F4B fighters. 342FH-3B26916-Y1C-23-32-232-Left-Side 342FH-3B26917-Y1C-23-32-232-Left-Rear The Altair came about during that run of great looking and performing aircraft the Vega, Sirius,Altair and Orion from Lockheed.The Altair boasted having the first successful fully retractable landing gear.  342FH-3B26918-Y1C-23-32-232-Front
