Brand new condition, never-issued circular slide rule and Takeoff and Landing Data T. Computer for the Boeing B-47B, B-47E, RB-47E and RB-47K six-engine aircraft equipped with the General Electric J-47-25 and -25A engine. The six-engine Boeing B-47 jet bomber first flew in 1947, entered USAF service in 1951, served with the Strategic Air Command until 1967 (RB-47H) and the Military Airlift command until 1969 (WB-47E).The last flight of ANY B-47 was in 1984 when a B-47E that was previously transferred to the NAVY was restored to airworthy condition and flown to the Castle AFB Museum (see last photo). The B-47 was featured in Paramount Pictures 1955 film Strategic Air Command starring James Stewart and June Allyson. This flight computer was manufactured in 1963 by Felsenthal Instruments Company of Chicago, makers of many different types mechanical computers for both industry and the military. This item is in new condition, along with the case and 21-page manual.
The outer edge of the LANDING side of the computer features a circular slide rule with C and D scales as with traditional circular rules. With an eight-inch diameter, the C and D scales equate to a linear slide rule over 24 inches long.Various parameters including runway length, pressure altitude, outside air temperature, runway conditions (RCR) and gross weight allows the operator to determine touchdown speeds and stopping distances. The TAKE-OFF side of the computer similarly allows the operator to determine takeoff distance and timing based on similar parameters. Please see my detailed photos for the many inputs available to accurately compute takeoff and landing performance data. The illustrated 21-page manual explains in detail how to perform each of these computations. The Smithsonian Institution has this same computer in their collection. Please advise if you require additional information or photographs. The item "Boeing B-47 Circular Slide Rule and Takeoff/Landing Data Computer" is in sale since Monday, April 1, 2019.
