Abstract
Description
本出願は、2002年2月8日に提出された米国特許仮出願第60/355,270号の利点を請求するものである。
T=ρAEXITVEXIT 2 T=14.2AEXIT 1/3(H.P.)2/3
ここで、ρは空気の密度、AEXITは後部開口54の出口面積、VEXITは後部開口54の出口での流れの速度、H.P.はエンジンの馬力である。図11A〜Bに示すように、ベーン64を使用して流れを45度偏向した場合、ナセル16の有効出口面積8(図11B)は41%大きくなる。出口面積の41%の増加は、同じエンジン出力に対して12.24%の推力の増加をもたらすことが予測されており、これは、流れの偏向を45度に制限することの他の利点である。
