Sikorsky To Acquire Schweizer Aircraft 

Sikorsky's pending acquisition of Schweizer Aircraft will enable the helicopter giant to diversify quickly into nontraditional markets and gain access to a rapid-prototyping organization that has penetrated a variety of aerospace and defense sectors.

Schweizer, for its part, will be able to call on Sikorsky's greater resources in developing new products. It also will gain the marketing savvy and reach, as well as the financial clout, it needs to grow and prosper, said President Paul Schweizer.

Pratt and USAF partnership creating life-extension plan for F100 family 

Pratt & Whitney and the Air Force have developed an engine life-management program for the F100 family that will maintain the engines' current safety, reliability and readiness levels as the military extends frontline deployment to periods greater than two and three times an engine's design life.

USAF Eyeing Larger Scramjets 

Scientists and engineers at the U.S. Air Force Research Laboratory are examining technologies that could result in the development of supersonic combustion ramjets 10 times larger than existing ground test demonstrators.

"We know how to make our current two-dimensional scramjet work, and it seems that it's good enough to fly and validate our technologies. It's also the right size for the hypersonic cruise missile mission," Bob Mercier said. He's the deputy for technology in AFRL's aerospace propulsion division here.

A380 Powerplants Begin Flight Tests Next Year 

Engine-makers General Electric, Pratt & Whitney and Rolls-Royce are moving quickly to certify their powerplants for the Airbus A380 mega-transport, which is scheduled to begin flight test early next year.

Rolls-Royce Developing Advanced Fadec for Its Large-Engine Line 

Rolls-Royce Corp. is developing an advanced full-authority digital engine control (Fadec) for its large-engine line that should boost functionality and processing speed while reducing cost.

New Markets Are Being Found for the T800 Engine 

T800 engine makers Rolls-Royce and Honeywell are pursuing an aggressive strategy to make the propulsion project viable following cancellation of the Comanche helicopter program and the loss of their primary market.

Today, the main focus of the Light Helicopter Turbine Engine Co. (LHTEC)--the joint company formed to manufacture and support the T800--is on a range of offshore projects that, taken together, could eventually bring T800 production back to Comanche-era levels.

Inlet Offers Supersonic Performance Benefits 

NASA Glenn Research Center engineers have concluded Phase 2 testing of an innovative, external compression inlet that could be used on manned and unmanned supersonic aircraft.

Called the Parametric Inlet, the unit was originally developed by TechLand Research in conjunction with Boeing. NASA Glenn's role has been to conduct extensive amounts of computational fluid dynamics work. Wind tunnel tests of the inlet in 2003 were aimed at verifying its basic performance. The latest trials, totaling some 25 hr., were focused on optimizing inlet design.

Trent 1000 Will Share Features With A380's Trent 900 

Rolls-Royce's design for the Trent 1000, an engine selected as one of the two propulsion offerings for Boeing's 7E7 transport, will borrow heavily from the 81,000-lb.-thrust Trent 900, Rolls' powerplant for the Airbus A380 mega-transport.

The intermediate-pressure compressor, high-pressure compressor, tiled combustor and turbines of the new powerplant all will be scaled from similar components used in the Trent 900.

Upgrading F110s Will Keep Them, F-16s They Power, Viable Until Aircraft Retires in 2025 

A service life extension program now being explored by the U.S. Air Force and General Electric for about 850 F110 fighter engines could eventually save the service $1 billion, over and above program costs, if implemented.

Two engines demonstrating the potential improvements will be on test by the end of the month, one at the Air Force's Arnold Engineering Development Center near Tullahoma, Tenn., the other at GE facilities in Evendale, Ohio.

Propulsion Tests Link IHPTET Initiative to JSF's F136 Engine 

Advanced gas generator trials have verified performance of the high-efficiency, low-smoke combustion system slated for use in the General Electric/ Rolls-Royce F136 Joint Strike Fighter alternate engine that will be tested this summer.

Pratt Is Testing the First SDD Stovl Propulsion System for the Joint Strike Fighter 

Beating a contractual deadline by about six weeks, Pratt & Whitney is testing the first system development and demonstration (SDD) Stovl propulsion system for the F-35.

Ongoing Tests Help Define GE's 7E7 Powerplant 

General Electric expects to begin detailed design of its GenX engine for Boeing's 7E7 transport in January, after completing extensive rig and component tests later this year.

By 2005, GE will conduct a variety of investigations, including 11 rig tests, some of which are already underway. As part of those evaluations, GE engineers will explore designs for the engine's fan blades, compressor, combustor and low- and high-pressure turbine blades.

Being Left Off the 7E7 Is a Mixed Bag for Pratt 

Pratt & Whitney's failure to secure a place on Boeing's 7E7 transport raises serious doubts about the company's future capability to independently develop and manufacture large commercial gas turbine engines.

A survey of its civil product line shows:

*The 37,000-43,000-lb.-thrust PW2000 is used on the Boeing 757, which will end production later this year. The engine also powers the Ilyushin Il-96, which has yet to garner significant orders.

PUTTING F135 TO THE TEST 

Pratt & Whitney's F135 system and development demonstration (SDD) test program is quickly gaining momentum with seven engines planned to be under evaluation by midsummer.

FX631--the first of the SDD F135s--began running at the company's West Palm Beach, Fla., test center in October and has accumulated more than 246 hr. Initial trials examined sea-level operability, fan performance and augmentor operability of the conventional takeoff and landing (CTOL) configured powerplant.
