Pratt & Whitney TF30-P-6E Turbofan Engine
Pratt & Whitney developed the TF30 turbofan engine as a private venture, originally working with Douglas Aircraft in early marketing considerations for the DC-9 small jet transport. However, what was a roughly half-scale version of the earlier JT3D ended up with no commercial application, but did find substantial military application, resulting in the first American turbofan equipped with an afterburner.
The engine, rated in the 89,000 N (20,000 lb) thrust class, completed its official military qualification tests in 1965, and powered the Ling-Temco-Vought (LTV) A-7A, B, and C Corsair II; General Dynamics F-111; and Grumman F-14A Tomcat aircraft. Production of the TF30 series stopped in 1986.
The museum's TF30, built by Pratt & Whitney without an afterburner in 1966, powered an LTV A-7A.
