Tamarack Aerospace has unveiled the first of what it promises will be a series of active winglet systems designed to relieve wing bending loads caused by winglets. The company’s active technology load alleviation system (Atlas) should be certified and available for installation on Cirrus SR22 G1 and G2 piston singles early next year, but Tamarack is also testing Atlas, which includes new winglets, on a Cessna CitationJet 525. Tamarack brought the Atlas-equipped CitationJet to the NBAA Convention in Orlando and gave demonstration rides during the show.
According to Unison Industries, its new dual direct spark ignition system (DDSI) successfully lit the Pratt & Whitney RL 10A-4-2 engine on the Lockheed Martin Atlas V Expendable Launch Vehicle’s Centaur upper stage. Launching from Cape Canaveral on August 21, the Centaur’s first RL 10A-4-2 main engine started after the separation of the first stage after just four-and-a-half minutes.
