| | | | The picture below shows larger front and back views of this Old General Electric S.A.E.D. T64 Aircraft Engineers Manufacturing Employee Celluloid Badge. The oval badge is not dated but it is believed to be from the 1950s or 1960s. It is in dark or Navy blue and white. It has a union marking and the button reads as follows: GE
S. A. E. D.
T64
MANUFACTURING The pinback button measures about 2-3/4'' x 1-3/4''. It appears to be in excellent condition except for a small area of celluloid (upper left) which has come loose from the edge as pictured. Below here, for reference, is some additional information: General Electric T64
From Wikipedia, the free encyclopedia Type: Turboshaft
National origin: United States
Manufacturer: GE Aviation
First run: (T64-GE-2) March 1959
Major applications: Lockheed AH-56 Cheyenne, Alenia G.222, de Havilland Canada DHC-5 Buffalo, Sikorsky CH-53 Sea Stallion, Sikorsky CH-53E Super Stallion. The General Electric T64 is a free turbine turboshaft engine that was originally developed for use on helicopters, but which was later used on fixed wing aircraft as well. General Electric introduced the engine in 1964. The original engine design included technical innovations such as corrosion resistant and high temperature coatings. The engine features a high overall pressure ratio, yielding a low specific fuel consumption for its time. Although the compressor is all axial, like the earlier General Electric T58, the power turbine shaft is coaxial with the HP shaft and delivers power to the front of the engine, not rearwards. Fourteen compressor stages are required to deliver the required overall pressure ratio. Compressor handling is facilitated by 4 rows of variable stators. Unlike the T58, the power turbine has 2 stages. Later versions of the engine produce from 3,925 to 4,750 shp (2,927 to 3,542 kW). The engine was designed to accommodate different gearboxes or shaft drives, for helicopter or turboprop fixed wing applications. The engine could be operated continuously at angles between 100 degrees upward and 45 degrees downward for STOL or helicopter applications. |
