Standards establish the riser angle limits for drilling and nondrilling operations with the riser connected. The basis required to minimize wear during rotation and tripping of the drill pipe. Limits are also necessary to assure safe operating conditions for landing casing hangers, subsea, and product...
Many airplanes, in particular sailplanes, have such high glide ratios that landing becomes difficult. For this reason, they are equipped with speed brakes or spoilers, which are panels that deflect from the wing surface and cause flow separation, increasing drag and reducing lift. The same ...
The indicator, motivated by gravity-responsive means, traverses the line of sight of the pilot or gunner so as to permit such pilot or gunner to maintain his eyes upon the target and at the same time receive indications concerning the angle of the dive, thereby obviating the necessity of ...
As one fundamental control mode in these missions, flight-path angle consensus tracking control achieves motion synchronization of the unmanned aircraft during the climb [5], steady wing-level flight, and landing [6]. However, compared with consensus control of other aircraft states (such as pitch...
