Air Force Introduction To Aerodynamics Takeoff And -

atmosphere of earth wikipedia - the atmosphere of earth is the layer of gases commonly known as air that surrounds the planet earth and is retained by earth s gravity the atmosphere of earth protects life on earth by creating pressure allowing for liquid water to exist on the earth s surface absorbing ultraviolet solar radiation warming the surface through heat retention greenhouse effect and reducing temperature, flight dynamics fixed wing aircraft wikipedia - flight dynamics is the science of air vehicle orientation and control in three dimensions the three critical flight dynamics parameters are the angles of rotation in three dimensions about the vehicle s center of mass known as pitch roll and yaw aerospace engineers develop control systems for a vehicle s orientation attitude about its center of mass, helicopter facts history types britannica com - helicopter aircraft with one or more power driven horizontal propellers or rotors that enable it to take off and land vertically to move in any direction or to remain stationary in the air other vertical flight craft include autogiros convertiplanes and v stol aircraft of a number of configurations, air crash investigation series tv tropes - mayday also known as air emergency and air disasters in the united states and air crash investigation in the uk and australia is a canadian documentary series about aircraft accidents and incidents episodes usually start in medias res while the disaster is underway following them with a sequence, charles lindbergh and the 475th fighter group - in support of the sansapor invasion a raid had been slated for the next day but bad weather delayed the mission until 27 july at 0745 the group lifted off to escort the first u s strike on halmahera one of two major islands in the molucca group air intel estimating 150 aircraft scattered over three fields 75 to 100 probably fighters, vfrweather com visual flight rules aviation weather - visual flight rules rules that govern the procedures for conducting flight under visual conditions the term vfr is also used in the united states to indicate weather conditions expressed in terms of visibility distance from cloud and ceiling equal to or better than specified minima vfr weather minimums, winglets and sharklets the flying engineer - winglets an inspiration from nature the high pressure on the lower surface of the wing creates lateral airflow outwards or away from the fuselage towards the wingtip where on account of relatively lower air pressure above the wing tends to spill over and swirl around the wingtip to form a vortex creating additional drag described as induced drag thereby reducing aerodynamic efficiency
