Preiss RHJ-7

In 1966 Henry Preiss converted an all metal Schreder HP-14 into a 2-place ship with side-by-side seating (two sets of rudder pedals and a center control stick with a bar that swings from one side to the other) and a fixed landing wheel. The design used standard HP-14 wings with a 2-ft center section added in the fuselage.

Preble-Rekar Airship

A never-completed 250 foot rigid airship, 24 feet in diameter, under construction during 1909-1910 by the Preble-Rekar Airship Company of Portland, Oregon.

Its dimensions were to have been 250 feet in length and 25 feet in diameter. Apparently bankrolled by Oregon investors, the Preble-Rekar Airship Company of C. H. Preble and J. J. Rekar (Rekar of San Francisco, CA), set up shop in Portland. The structure was made of spruce and no nails or bolts were used.

Pratt & Whitney Canada PT6T / T400

PT6T-3B

The Pratt & Whitney Canada PT6T Twin-Pac is a turboshaft engine designed for helicopters. Manufactured by Pratt & Whitney Canada, its first application was in the Bell 212 and UH-1N Twin Huey helicopter family. The PT6T Twin-Pac consists of two PT6 power turbines driving a common output reduction gearbox, producing up to 2,000 hp at 6,000 rpm. The engine is designated T400 by the U.S. military.

The U.S. military came very close to not procuring the UH-1N Twin Huey because of the PT6T. The purchase of the aircraft for U.S. military use was opposed by the Chairman of the House Armed Services Committee at the time, Mendel Rivers. Rivers took this position because the PT6T was produced in Canada. The Canadian government had not supported U.S. involvement in Vietnam, and had opposed U.S. policies in southeast Asia, as well as accepting U.S. draft dodgers. Rivers was also concerned that procurement of the engines would result in a negative trade deficit situation with Canada. Congress only approved the purchase when it was assured that a U.S. source would be found for the PT6T engines. This source was Pratt & Whitney Engine Services in Bridgeport, West Virginia, which was established in 1971 to assemble and test new T400-WV-402 engines. As a result, the U.S. military ordered 294 Bell 212s under the designation UH-1N, with deliveries commencing in 1970.

Pratt & Whitney Canada PW600 / PW610 / PW615 / PW617 / PW625

PW610F

The Pratt & Whitney Canada PW600 series is a family of very small turbofan engines developed by Pratt & Whitney Canada for use in very light jets. Designed with scalability in mind, the engines can produce between 900 lbf (4,000 N) and 3,000 lbf (13,000 N) of take-off thrust.

First run of the 2,500 lbf (11,000 N) thrust PW625F demonstrator engine was on 31 October 2001. P&WC began work on the 900 lbf (4 kN) thrust PW610F engine, destined for the Eclipse 500, in 2002. The engine was certified by the Canadian authorities on the 27 July 2006. The first Eclipse 500 aircraft, powered by two PW610Fs, was delivered to a customer on 31 December 2006.

With a 14.5 inch (36.83 cm) diameter fan, the PW610F is one of the smallest turbofans to enter production. Little is known about the engine cycle, although the bypass ratio is believed to be about 1.83. Driven by a single-stage low pressure (LP) turbine, the single stage fan is an advanced snubberless design, with wide chord blades integral with the rotor hub. The newly patented high pressure (HP) compressor comprises a diagonal (i.e. mixed) flow stage, supercharging a conventional centrifugal blower, the whole being driven by a single stage HP turbine. A reverse flow combustor and forced mixer/common exhaust are also featured in the design. Dual lane Full Authority Digital Engine Control (FADEC), for smoother, more reliable, operation, is included in the specification. Hispano-Suiza Canada is currently designing and manufacturing the FADEC for this engine.

The larger, 1,350 lbf (6,000 N) thrust, PW615F has a 16 inch (40.64 cm) diameter fan and is aimed at the Cessna Citation Mustang. This engine was certified in December 2005, with first deliveries in March 2006. The Mustang aircraft was certified on 8 September 2006, and deliveries began in 2007. This engine will also be used in the upcoming Eclipse 400, but it will be limited to 1,200 lbf (5,300 N) thrust. Bypass ratio of PW615F amounts to 2.8.

PW610F-A

The PW610F achieved its rated takeoff thrust of 900 pounds after only five hours during the test run, which took place May 4, 2004. The first flight of the PW610F engine took place December 16, 2004 (on P&WC’s Boeing 720 flying test bed). During the 6-hour flight, a number of tests were performed, including performance characterization and an altitude re-light. The PW610F had previously completed more than 500 hours of ground testing. PW610Fs also meet Stage 3 noise requirements.

So far, the 1,615 lbf (7,180 N) thrust PW617F, with a 17.6 inch (44.7 cm) diameter fan and bypass ratio of 2.7, is the largest in the family and is designed to power the Embraer Phenom 100. The engine first ran on 29 June 2006, with certification expected in the 4th quarter of 2007. First delivery of a production model is expected in March 2008.

As of October 15, 2006, fifty PW610Fs and PW615Fs had been delivered by P&WC.

Pratt & Whitney Canada PW300 / PW305 / PW306 / PW307 / PW308

PW308

The Pratt & Whitney Canada PW300 series is a family of turbofan engines developed by Pratt & Whitney Canada specifically for business jet applications.

The basic configuration of the PW300 is as follows: single stage fan, driven by a three-stage low pressure turbine, supercharging a four-stage axial/single stage centrifugal high pressure compressor, driven by a two stage high pressure turbine. An annular combustor is featured. Some versions have an unmixed exhaust, but the PW306 and PW308 include a forced mixer. A Full Authority Digital Engine Control (FADEC) system is incorporated.

The PW307A is a new centre-line engine developed specifically for a tri-jet application on the Dassault Falcon 7X. The PW307 was certified by Transport Canada in March 2005.

The PW308A has been chosen to power the Scaled Composites White Knight Two, the launch aircraft for Virgin Galactic’s SpaceShipTwo.
