Turbine-engine technology development is going in two directions. One is the development of new technology to push the envelope of performance, operational safety, maintainability and reliability. The other is to refine and update existing engines for long-term use, especially in light of more stringent Stage 4 requirements and existing Stage 3 rules.

Aero Toy Store has been appointed the factory authorized representative of Aerion for the sale of the company’s supersonic business jet. The agreement allows the initial sale of 12 of the new jets, which will cruise at speeds up to Mach 1.6 at altitudes of up to 51,000 feet. It has a range of 4,000 nm.

Sikorsky Aircraft has selected Eaton Corp. (Stand No. P39) to design and manufacture the primary hydraulic power generation system for the U.S. Marine Corp’s new heavy-lift CH-53K helicopter.

During the development phase of the program, which runs through 2014, Eaton will provide the systems and components for five to 10 shipsets, in addition to a number of test sets. The Marines expect to buy more than 156 CH-53Ks.

The efficiency of the gas turbine engines that power today’s commercial and military aircraft is approaching the highest level possible with current turbofans. But a totally new technology being pioneered by GE Aviation and researchers worldwide promises far simpler, more efficient engines that will extend aircraft range, cut fuel costs and reduce emissions.

France-based engine manufacturer Snecma has reported “positive results” for the first 35 ground test hours of its Silvercrest core engine. In an unusual move, the company has begun the test program without announcing a launch application for the new turbofan, which is targeted for applications on future super-midsize to large business jets. The core engine achieved “all the expected performance objectives” for these combustion trials.

Boeing 737s, including the derivative BBJ, have been hit by another emergency AD affecting the twinjet’s fuel pumps. The latest directive (AD 2002-24-51) results from overheating pumps and requires affected aircraft to continue to carry the same minimum fuel quantities as required by the September 30 emergency AD dealing with chafed pump wiring.

BBA Aviation-owned engine repair and overhaul company Dallas Airmotive plans to open a regional turbine center next month at the Washington County Airport just south of Pittsburgh. The 5,300-sq-ft facility initially will provide hot-section inspection services for Pratt & Whitney Canada PT6A turboprops and JT15D turbofans, as well as fan repairs on JT15Ds and power-section repair on PT6As.
