The left laminar flow wing section. Natural laminar flow is opposed to hybrid laminar flow artificially induced through hardware. It is difficult to industrialise a wing smooth enough to sustain the laminar flow in operation, due to having very low design and manufacturing tolerances, leading-edge retractable slats, and fasteners, that is aerodynamically robust enough, and can withstand ...
The Breakthrough Laminar Aircraft Demonstrator in Europe (BLADE) is an Airbus project within the framework to flight-test experimental laminar-flow wing sections on an A340 from September 2017. [4] Other examples of hardware that have been developed with the support of Clean Sky include:
With a legacy of more than 100 years, the Better Business Bureau (BBB) is the go-to watchdog for evaluating businesses and charities. The nonprofit organization maintains a massive database of ...
The Better Business Bureau (BBB) is an American private, 501(c)(6) nonprofit organization founded in 1912. BBB's self-described mission is to focus on advancing marketplace trust, [2] consisting of 92 independently incorporated local BBB organizations in the United States and Canada, coordinated under the International Association of Better Business Bureaus (IABBB) in Arlington, Virginia.
Laminar Z9 12.6 Introduced in 2010, extra small sized model for small pilots. Its 9.61 m (31.5 ft) span wing is a "topless" design without a kingpost. The nose angle is 132°, wing area is 12.52 m 2 (134.8 sq ft) and the aspect ratio is 7.38:1. Pilot hook-in weight range is 55 to 75 kg (121 to 165 lb). DHV certified as Class 3. [2] Laminar Z9 13.2
Laminar flow airfoils were developed in the 1930s by shaping to maintain a favourable pressure gradient to prevent them becoming turbulent. Their low-drag wind tunnel results led to them being used on aircraft such as the P-51 and B-24 but maintaining laminar flow required low levels of surface roughness and waviness not routinely found in ...
The Edgley EA-7 Optica is a British light aircraft designed for low-speed observation work, and intended as a low-cost alternative to helicopters.The Optica has a loiter speed of 130 km/h (70 kn; 81 mph) and a stall speed of 108 km/h (58 kn; 67 mph).
WASHINGTON (Reuters) -The U.S. Federal Aviation Administration said on Monday it would require inspections of Boeing 787 Dreamliners following an incident in March when a LATAM Airlines plane went ...
