Aviation Partners Boeing last month announced that, after launching on the Boeing 737 NG, split scimitar winglets can now be fitted on the Boeing BBJ family. The new split scimitar winglets offer a significant reduction of drag compared to the non-winglet-equipped Boeings and a noticeable drag reduction for those equipped with Aviation Partners Boeing blended winglets.
Aviation Partners (Booth No. C8114), in cooperation with Boeing, is launching its new Split Scimitar Winglet program for Boing BBJs. Split Scimitar Winglets are already available for 737 NGs.
The Split Scimitar Winglet modifies the existing blended winglet on the BBJ by adding a Scimitar-tipped ventral strake, reinforced internal winglet structure and replacement of the aluminum winglet tip caps with more aerodynamically shaped Scimitar tip caps.
The Administración Nacional de Aviación Civil Argentina has approved the first three of numerous STCs for Raisbeck Performance Systems for the Beech King Air. The current STCs are for Raisbeck’s dual aft body strakes for the 200/B200/B200GT series and 90/C90 series, and for wing lockers on the 90 series. Additional applications are currently proceeding through the ANAC approval process.
Denmark’s ScanTech has outfitted a King Air 200 from Swedish air ambulance operator Svensk Flygambulans AB with five Raisbeck EPIC Performance Systems at its facility in Sindal. The retrofits included Hartzell/Raisbeck turbofan propellers, high-flotation gear doors, dual aft body strakes, enhanced-performance leading edges and ram air recovery systems.
Flight testing of BLR Aerospace’s Bell 212 FastFin modification has demonstrated improved performance that will allow the 212 to carry more weight to higher altitudes than standard 212s, according to BLR. The Everett, Wash. company conducted the flight tests at the 9,927-foot airport in Leadville, Colo., late last year.
The U.S. Coast Guard (USCG) has signed a $260,000 contract with Boundary Layer Research (BLR) to adapt a NASA-patented technology for use on the Coast Guard’s fleet of HH-65 Dolphin helicopters.
Boundary Layer Research has won FAA approval for a hover-performance increase of up to 250 pounds for Bell 204Bs, 205A-1s and UH-1Hs fitted with its tailboom strake modification kits. Known as the Performance Pack, the new clearance is the result of high-density-altitude flight tests conducted last summer near Greybull, Wyo.
A September 7 information letter from Bell Helicopter warns Bell 206 and 206L operators of potential problems with STC'd Boundary Layer Research (BLR) tailboom strakes.
Bell Helicopter recently issued new information letters expressing concern about BLR Aerospace tailboom strakes. Bell issued a similar letter in 1995 when BLR obtained certification for use of tailboom strakes on Bell’s line of medium helicopters.
A fleet totaling 600 helicopters equipped with dual tailboom strakes from BLR Aerospace has reached the one-million flight-hour milestone, all the while earning accolades from operators, according to the Everett, Wash. company, which manufacturers aerodynamic enhancements.
