1. The passenger seat is behind the pilot's seat, aft of the wing aspect ratio to 28 : 1.
2. Due to the low wing aspect ratio ( around 1.5 ), drag is high at low speeds and the aircraft requires high thrust at take-off.
3. The bats have a wing aspect ratio of 6.1 and a wing loading of 6.7 N / m 2, which are both relatively low values for bats.
4. Such as : take-off and landing distances, max L / D, wing aspect ratio, tapor ratio, swept angle, incidence angle, dihedral angle, airfoils, wheel track, wheel base, quantity of fuel, etc . Too esoteric?
5. Among the penalties for stealth are lower engine thrust, due to losses in the inlet and outlet, a very low wing aspect ratio, and a high sweep angle ( 50?) needed to deflect incoming radar waves to the sides.
6. It's difficult to find wing aspect ratio in a sentence. 用wing aspect ratio造句挺難的
7. The F / A-18 pre-production wing has a relatively high wing aspect ratio for a fighter and originally was designed to have sufficient strength, and to be free from buckling or flutter issues, but no additional stiffness was added for static aeroelastic issues.
8. Paper models typically have a wing aspect ratio that is very high ( model sailplanes ) or very low ( the classic paper dart ), and therefore are in almost all cases flying at velocities far below their wing planform and aerofoil Critical " Re ", where flow would break down from laminar to turbulent.
9. Moreover, the performance of the glider continued to fall short of what they had calculated . ( The setbacks ) ultimately convinced them to undertake the all-important wind tunnel tests that enabled them to correct the flawed data they had inherited from others, and to investigate some key design issues, such as wing aspect ratio.
10. The Boeing 787, first flown in 2009, was the first commercial aircraft with 50 % of its structure weight made of carbon-fiber composites, along 20 % Aluminum and 15 % titanium : the material allows for a lower-drag, higher wing aspect ratio and higher cabin pressurization; the competing Airbus A350, flown in 2013, is 53 % carbon-fiber by structure weight.
