Phoenix Mill, Gloucestershire, England, UK: Sutton Publishing Limited. World Encyclopedia of Aero Engines, 5th Edition. Specific fuel consumption: 1.04 lb/hr-lb.Compressor: Single-Spool, 11-stage Axial.C-119 Flying Boxcar (civilian variant modification).ĭeveloped during the transition from piston-engined aircraft to jets, the J34 was sometimes fitted to aircraft as a supplement to other powerplants, as with the P-2 Neptune and Douglas Skyrocket (fitted with radial piston engines and a rocket engine, respectively). However, equipped with the J34 instead of its intended engines, it was seriously underpowered and could not exceed Mach 1 in level flight. The Stiletto was developed to investigate the design of an aircraft at sustained supersonic speeds. For instance, the Douglas X-3 "Stiletto" was equipped with two J34 engines when the intended Westinghouse J46 engine proved to be unsuitable. Contact Covington Aircraft today to set up your repair or maintenance visit, or learn more about our services.Built in an era of rapidly advancing gas turbine engine technology, the J34 was largely obsolete before it saw service, and often served as an interim engine. If you need assistance with your R985, we can help. Preliminary Performance Data on Westinghouse Electronic Power Regulator Operating on J34-WE-32 Turbojet Engine in Altitude Wind Tunnel The behavior of the Westinghouse electronic power regulator operating on a J34-WE-32 turbojet engine was investigated in the NACA Lewis altitude wind tunnel at the request of the Bureau of Aeronautics, Department of the Navy. The R985 Wasp Junior has certainly earned its place in aviation history, and continue to be used today. Whether you need repairs, maintenance, or an overhaul, it’s important to know more about your engine options. Many of the modern designs being released today are built on the foundation of the R985, and in many instances an engine with a different name will still be very close in design to this classic. While it was used throughout World War II, today the R985 has been used in agricultural aircraft, bush planes, and small personal aircraft. That means that if desired, aircraft owners could swap from one to the other. One of the more desirable things about the engine was that it and the larger R-1340 actually have the same mounting dimension. During engine operation, fluid leakage through clearances in the compressor section 10 contributes to system losses, making the operational efficiency of a turbine engine less than the theoretical maximum. The power is derived from a centrifugal supercharger, and the first design delivered about 300 horsepower although later models increased that level and by the time the C-series was released horsepower was increased to 600hp for takeoff and 525 for sustained flight. The compressor section 10 contains several areas in which there is a gap or clearance between the rotating and stationary components. The design uses a nine cylinder radial that is air cooled. More than 39,000 of the engines were built, and decades later many are still in use. The R985 Wasp Junior is probably one the most popular engines Pratt and Whitney released, and has found its way into civilian as well as military aircraft. Over the years it has found its way into numerous aircraft including: The Wasp Junior was designed as a smaller version of the R-1340, and was designed for mid to small sized aircraft. It’s also considered to be a classic, and the first run of the R985 started back in 1929. The First engine with Variable IGV s was the GE J85. if the turbine wasnt burned up change the ignittors open the engine compressor cap to check there was no compressor damage change the filters and push her back out of the door. This radial engine is versatile, delivers good power, and is very reliable. Westinghouse J34-WE48 with No fan, Compressor and 2 stage turbine. There are numerous engines in the industry, but one of the most popular is the R985 from Pratt and Whitney. Your aircraft’s engine is the most important part of its construction, and at Covington Aircraft we feel that taking the time to understand just a little more about it is a good idea whether you’re a pilot, a fleet manager, a mechanic, or just an owner of a single plane.
