Lift is always accompanied by a drag force, which is the component of the surface force parallel to the flow direction. Lift is mostly associated with the wings of fixed-wing aircraft , although it is more widely generated by many other streamlined bodies such as propellers , kites , helicopter rotors , racing car wings , maritime sails , wind ...
Also, the U.S. Air Force dropped 114,810 tons of bombs on the North Vietnamese at Khe Sanh, roughly as many as dropped on all of Japan in 1945 during World War II. [ 139 ] It is also possible that Giáp never intended to capture Khe Sanh in the first place, and that Khe Sanh was used as a diversion for the upcoming Tet Offensive .
With further North Vietnamese offensives in the offing, the American government found itself presented with a double-edged dilemma. L'Armee Clandestine was the only Lao military force still ready to fight in northern Laos—but barely ready. Continued defense of Long Tieng could lead to their defeat and loss of the war.
The Egyptian Air Force is to operate the T-50/FA-50 jet as a replacement to their aging fleet of Alpha Jets and Chinese Karakorum-8 trainer jets. [citation needed] Pakistan: The Pakistan Air Force is considering the purchase of the South Korean KAI T-50 Lead-in Fighter Trainer (LIFT) to revamp its air force training program. [177]
Dau Tieng helipads, 23 September 1967 Air controllers of the 2nd Battalion, 28th Infantry calling in aircraft to lift troops for redeployment, 18 February 1970. The base was established in October 1966.
The section lift coefficient is based on two-dimensional flow over a wing of infinite span and non-varying cross-section so the lift is independent of spanwise effects and is defined in terms of ′, the lift force per unit span of the wing. The definition becomes
When a fluid flows around an object, the fluid exerts a force on the object. Lift is the component of this force that is perpendicular to the oncoming flow direction. and as a mathematician rather than an aerodynamic engineer lift=0 means actually zero, as opposed to "too small to be useful or significant." One of the arts of engineering is to ...
About 100 South Vietnamese soldiers deployed around the site, which was near the site of an engagement with the Viet Cong the previous night. Out of 314 people on board, the death toll included 78 children, 35 Defense Attaché Office employees and 11 U.S. Air Force personnel; there were 176 survivors.
