Hi Piet, here's new engine start Saturday morning in four years, now with propeller. Check list complete, here we go.... After being befogged in oily smoke, I received a moralizing lecture from an adjacent owner....!!
This engine was one of four that was installed in the DC-7s that I flew years ago. The design was began in 1935 or so and the first one ran in 1937. It has 18 cylinders (2 rows of 9) 3350 cu.in displacement and the ones I remember would produce 3400 HP for takeoff and 2900 continuously. This model, like the DC-7 ones, has 'power recovery turbines'. These are the green round things seen on the top and bottom. There are 3 and the exhaust of 6 cylinders went into them and their output shafts were connected to the crankshaft via oil clutches. They would produce roughly 500 extra HP during takeoff. Pretty incredible considering they didn't have computer-assisted drafting or even electronic calculators back then. If close was good enough, you used a slide rule. If it had to be exact, you wrote out the math longhand..........
RR KNL This engine is from Lockheed P2-V7 and not from DC-7. DC-7 had direct injected engines CW-TC-18 EA1. P2-V7 had carburetor engines CW R-3350 32WA.
@@turbocompound That's interesting, I knew there were several versions of them. The early ones had a magnesium crankcase and after a few spectacular fires that could not be extinguished, they went to iron, I believe.....not sure though.
A VARIG tinha Lockheed Super L1049 Constellation com esses motores R-3350. A VARIG usava esse avião especialmente para voos para JFK. Com dos chegada de 2 707-441 (PP-VJA e PP-VJB) E dos caravelles, A VARIG usou os Constellation motores R-3350 para vôos domésticos e com a chegada dos DC-10-30, os constellation motores R-3350 passaram a fazer somente voos cargueiros.
Hey I noticed these videos were uploaded quite some time ago but I was reaching out in the comments section in the hopes I could get in touch with someone who has a little more information regarding the Curtiss Wright 3350 engine. I work for a construction testing facility located in Southern California and we use this engine for some of our testing done at the facility. Unfortunately our current engine is experiencing some serious issues and were are trying to locate a new running engine. In addition to a getting a new motor we are hoping to meet or talk with an expert or someone who can help guide us or assist us in making sure our engine set up runs and performs optimally. If anyone at all has knowledge about these engines or could put me in contact with someone who does I would be forever grateful.
