BLR EARNS ADDITIONAL FAA APPROVALS
Everett, WA March 26, 2001: The FAA has approved the BLR Strake Kit developed by Boundary layer Research, Inc. (BLR) for use by private and commercial operators of Bell 205, 205A-1, 205B and 212 helicopters. The approval was issued as a Supplemental Type Certificate (STC) for the modification and is based on technology patented by NASA Langley Research and licensed to Boundary Layer Research, Inc. exclusively for commercial development. Under the licensing agreement NASA receives royalties on kit sales. The BLR Strake modification is sold in kit form and can be installed in the field environment within a day using two technicians. Installed weight of the kit is 5.5 lbs. The BLR strake device works by manipulating boundary layer airflow produced by the helicopters main rotor to improve aircraft hover stability, climb and cruise characteristics. The technology is the result of more that eight years of wind tunnel and flight-testing completed by a team of NASA and U.S. Army researchers. BLR has plans to adapt the device to fifteen different models of helicopters over the next few years. Last May the Company received its first FAA STC approval for use of the strake kit on civil versions of the UH-1H "Huey" helicopter.

Boundary Layer Research, Inc. is a Washington State based company that designs and develops products based on boundary layer airflow. Mr. Robert Desroche founded the company in 1992. BLR products have already brought performance enhancements to more than sixty models of aircraft in over ninety-six countries. Modifications include vortex generators, winglets, wing-tip tanks, airframe strakes, flow modifier, landing gear upgrades and the NASA patented Tailboom Strakes.
