Relation between angle of attack and lift Angle of attack

-


a typical lift coefficient curve.


the lift coefficient of fixed-wing aircraft varies angle of attack. increasing angle of attack associated increasing lift coefficient maximum lift coefficient, after lift coefficient decreases.


as angle of attack of fixed-wing aircraft increases, separation of airflow upper surface of wing becomes more pronounced, leading reduction in rate of increase of lift coefficient. figure shows typical curve cambered straight wing. symmetrical wing has 0 lift @ 0 degrees angle of attack. lift curve influenced wing shape, including airfoil section , wing planform. swept wing has lower, flatter curve higher critical angle.

the ford model t first commercial flex-fuel vehicle. engine capable of running on gasoline or ethanol, or mix of both. the 1996 ford taurus first flexible-fuel vehicle produced versions capable of running either ethanol (e85) or methanol (m85) blended gasoline. the first commercial flexible fuel vehicle ford model t, produced 1908 through 1927. fitted carburetor adjustable jetting, allowing use of gasoline or ethanol, or combination of both. other car manufactures provided engines ethanol fuel use. ethanol disadvantaged frequent accusations ethanol producers collaborated bootleggers during prohibition. oil dominance motor fuel questioned in u.s. after 1973 oil crisis, resulted in gasoline shortages , awareness on dangers of oil dependence. crisis opened new opportunity ethanol, methanol , other alternative fuels. as response shock caused first oil crisis, u.s. government provided initial support develop alternative fuels, , time later, goal improve air quality. liquid fuels preferred o...
