Snecma is progressing with its plans to develop a turbofan in the 10,000-pound-thrust class. Last October, the French manufacturer revealed plans to enter the business jet engine market. Design of the Silvercrest powerplant is well under way and the core should run later this year.

French engine manufacturer Snecma is making progress with plans to develop a turbofan in the 10,000-pound-thrust class. The manufacturer revealed plans last October to enter the business jet engine market. Design of the Silvercrest powerplant is now well under way, and the core is scheduled to run later this year.
The Enstrom 480 series has an upgraded air conditioning unit that the FAA recently certified. “The condenser bypass makes this system more efficient than that of most of our competitors,” claimed Bayard duPont, director of product support for Enstrom Helicopter.
An elastomeric main rotor damper developed by Lord Corp. has gained U.S. Federal Aviation Administration certification for use on the Enstrom 480 light turbine helicopter. The damper has been incorporated into new production models and is available for retrofit into existing helicopters in the field.
Enflite, Inc. (LifePort Booth No. 4620) is at NBAA’06 with a new line of products and improvements for the business jet cabin.
The Georgetown, Texas company is especially well known for its cabin pocket doors, and is introducing a slide-rail system and counter-balance spring said to ensure smooth and consistent operation.
Regulation may be in the air for the cabins of commercial aircraft, though it is unclear which is more infectious: airborne particles or hysterical legislation. On April 6, the House subcommittee on aviation, chaired by John Mica (R-Fla.), discussed efforts to prevent a pandemic–an epidemic across international boundaries affecting masses–and debated whether the problem can best be addressed through legislation or common sense.
The American Society of Heating, Refrigerating and Air-conditioning Engineers (ASHRAE) has proposed a standard that will define air quality and comfort levels on commercial airplanes, but it is not related to any FAA study or any planned rulemaking.
Robinson now offers air conditioning in the R44 Raven II. Each seat is equipped with an individual overhead vent providing a total airflow of 250 cubic feet per minute. The 33-pound system, mounted on the aft cabin bulkhead and thus preserving all four baggage compartments, uses the latest automotive refrigerant and has a cooling capacity of 12,000 BTU per hour.
Enstrom has received certification for new elastomeric dampers for its 480B. The dampers, from Lord Corp., are being incorporated on productionaircraft and can also be retrofitted. They replacehydraulic dampers and, says Lord, improve ground operation, ride and handling qualities. They are also expected to cut maintenance costs.
