wave drag उदाहरण वाक्य

उदाहरण वाक्य

1. Boeing stated that the CFTs do not add any cruise drag but acknowledged a negative impact imposed on transonic acceleration due to increased wave drag.
2. A rounded edge would behave as a blunt body in supersonic flight and thus would form a bow shock, which greatly increases wave drag.
3. In order to minimize the wave drag, the curvature of the aircraft should be kept to a minimum, which implies much higher fineness ratios.
4. In 1947, studies into wave drag led to the development of " perfect " shapes to reduce wave drag as much as theoretically possible.
5. In 1947, studies into wave drag led to the development of " perfect " shapes to reduce wave drag as much as theoretically possible.
6. German research during the Second World War had shown the onset of wave drag was greatly reduced by using airfoils that varied in curvature as gradually as possible.
7. A "'supercritical airfoil "'is an airfoil designed, primarily, to delay the onset of wave drag in the transonic speed range.
8. At some point, though, the forward speed of the plane combined with the rotational speed of the propeller will once again result in wave drag problems.
9. Boats can go faster, the narrower they are, because a smaller cross-sectional area reduces wave drag and gives a sharper angle to the bow.
10. By using a conventional rectangular wing the high-speed drag was greatly increased ( see wave drag ) but the low-speed lift was likewise greatly increased.
