Development of a New Flap for a Light Utility Transport Aircraft
نویسندگان
چکیده
The Bush Hawk XP, which is produced by Found Aircraft of Canada, is a small, piston-engined utility transport aircraft suitable for bushplane operations. The original version was made in the 1960s, and it uses a sealed, plain hinged flap. In the latest production version the gross weight is increased substantially, necessitating an improved flap design to achieve better airfield distances and climb performance. This paper describes the aerodynamic design and development of a new single-slotted flap for the Bush Hawk. The flap shape and locations when deflected were optimized using modern CFD methods, and wind tunnel tests were bypassed. The features of the flap aerodynamic design, the aircraft structure, and the flap drive systems are described. Flight test results are presented for the Bush Hawk with the new flap; they show outstanding performance in its category. continued on page 234 Figure 1.

From Wright Brothers 1903 to present day 2003, aeronautical technology has made a profound progress. This paper demonstrates the outcome of this progress in weight, wing area, and engine thrust in three categories of transport aircraft of short to long range, regional jets, and turbo-prop commuter aircraft. Also the paper includes those aircraft with distinct jump in aeronautical technology. Fe...

Background Traditionally, embryo incubation and assessment daily has been under a light microscope, these observations are inevitably restricted to specific times and considering that the development of the embryo is a dynamic process, several critical stages in between observations may go unnoticed. For this reason, the new technologies, time lapse monitoring, have focused on the research for ...
متن کاملA Comparative Review of Global Transportation Energy Outlook
In 2010, the global transport sector consumed about 2,200 million tons of oil equivalent. About 96% of this amount came from oil. It shows that more than 60% of the oil consumed globally goes to the transportation sector. Road transport accounts for the bulk of the transportation energy consumption. The light-duty vehicles (LDVs), including light trucks, light commercial vehicles, and minibuses...
