Sulzer Hydraulic Power Recovery Reaction Turbines can be used to capture lost energy There are two basic types of HPRT Impulse (Pelton wheel) and reaction type Generally, pumps are a means of fluid transport that convert mechanical energy into hydraulic energy Pumps increase fluid pressure and flow When process conditions call for pressureWright R3350 DuplexCyclone TurboCompound radial engine The first aircraft engine to be tested with a powerrecovery turbine was the RollsRoyce Crecy This was used primarily to drive a geared centrifugal supercharger, although it was also coupled to the crankshaft and gave an extra 15 to 35 percent fuel economy 3The Argus was fitted with four 3,700 HP 18cylinder Wright R3350 981TC18EA1 Turbo Compound engines This engine had two rows of 9 cylinders and a piston displacement of 3,350 cubic inches (55 L) There was a singlestage 2speed centrifugal supercharger, plus 3 power recovery turbines (PRT's), which contributed up to 600 HP at maximum power

The civilian version of the R3350 used a turbocompound system that delivered better fuel efficiency and economy and the engine was favored for airline transports It incorporated a Power Recovery Turbine (PRT) which boosted horse power upIt's been done The Wright R3350 aircraft engine was eventually fitted with three Power Recovery Turbines, which recovered energy from the exhaust gases that was then coupled back to the main drive shaft Wright R3350 DuplexCyclone WikipediaThe exhaust restriction imparted by the three blowdown turbines used on the Wright R3350 is equal to a welldesigned jet stack system used on a conventional radial engine, while recovering about 550 hp (410 kW) at METO (maximum continuous except for takeoff) power In the case of the R3350, maintenance crews sometimes nicknamed the turbine the parts recovery turbine
The Wright R3350 DuplexCyclone was one of the most powerful radial aircraft engines produced in the United States It was a twin row, supercharged, aircooled, radial engine with 18 cylinders Power ranged from 2,0 to over 3,700 hp (1,640 to 2,760 kW), depending on the model Developed before World War II, the R3350's design required a long time to mature beforeTo build an R3350 Turbo Compound engine, Wright took an improved postwar model engine and sandwiched three power recovery turbines (PRTs) spaced at 1º intervals around the rear of the engine The addition of the three PRTs between the power and supercharger sections added only eleven extra inches overall length compared to a nonturbocompounded engineWright R3350 TurboCompound radial engine Two exhaust recovery turbines shown outside impellor casing area (top (silver) and lower (red blading)) that are geared to the crankshaft

This was called a "Power Recovery Turbine" (or PRT) and was common on DC7 and Lockheed Constellation aircraft, recovering about 500 net horsepower per engine But nothing is free in physics, and the cost here is weight and considerable complexity, plus an increase in backpressure, which always steals powerSomewhat slightly educated conjecture, but The DC7 was derived from the C74 Globemaster, a transport aircraft that had to be capable of loading and unloading large heavy items, so needed a relatively low ground clearance Lower ground clearanceThe turbine is usually mechanically connected to the crankshaft, as on the Wright R3350 DuplexCyclone, but electric and hydraulic power recovery systems have been investigated as well The XC69 however, was equipped with four Pratt & Whitney R2800 radial engines instead of the Wright R3350s used on production models (Lockheed had made that installation on the prototype to test the R

The supercharger is taken from a R3350 used on the Lockheed EC121 and the engine is fitted with Nitrous Oxide injection Normal rated power of a stock R3350 is 2,800 horsepower at 2,600 rpm and 45 inches of manifold pressure(Powerrecovery turbines, also known as 'blowdown turbines,' are velocity turbines PRTs are used on the Wright R3350 Turbocompound engine to extract energy from the exhaust gases and return it to the crankshaft by means of a fluid coupling The DC7B and later Constellation variants like the Super C and Super G used the Wright R3350 engines but added power recovery turbines, or PRTs These added about 550 maximum takeoff horsepower at sea level on a standard temperature and pressure day to the crankshaft through hydromatic transmission technology, or hydraulic pressure torque directly

The power recovery turbines used in large radial engines were nicknamed "parts recovery turbines" because they would "filter" out parts of the engine when it lost chunks of parts This often destroyed the turbine and its gearbox, causing a relatively minor engine failure to cost a lot more than it wouldPower Recovery Turbine (PRT), R3350 Engine Display Status This object is on display in the Boeing Aviation Hangar at the Steven F UdvarHazy Center in Chantilly, VASTACKS PRESSURE TURBINE Fig 1 1 Power recovery systems will be increased to approximately 100% of the power output There are two principal methods of recovering exhaust gas energy through the use of a turbine or turbines The impulse or blowdown turbine utilizes the kinetic or velocity energy of the gas
