The Airline Business, 2nd Edition

The airline is at present confronted with its longest and private obstacle so far: many airways are wasting hundred of hundreds of thousands folks funds, a number of have collapsed completely and others were rescued by way of their governments. This obstacle has been triggered by means of exterior shocks akin to the assault at the dual Towers in long island, the invasion of Iraq and the SARS epidemic.

8] presented five cases in their paper. 55). 1. Here, k D k L is the drag-to-lift ratio; α x =0 = β x =0 is the initial distortion, and, α x =0 = α ( 0 ) ; β x =0 = β ( 0 ) . There are two main questions about the calculations in [8]. 56) were not included and the results of variable ξ were presented. In fact, the calculation of variable ξ is followed by the calculation of the variables α , β , α 0 and β 0 . 55). They must put one more condition such as α0=β0 in their calculation so that to work out the four parameters, although this was not mentioned in their paper.

The asymptotic behavior of mass flow rate flow rate. Besides, a higher mass flow rate will arrive at a larger asymptote. This proportional relation between mass flow rate and inlet distorted velocity can also be seen from Fig. 13. In conclusion, a smaller inlet distorted velocity and larger flow angle may result in a low overall mass flow rate, even a back flow (Fig. 13). 2 . 0 Fig. 13. 4 Critical Distortion Line The results in previous paper [8], case 1, case 2 and case 4 expressed the distortion propagation with respect to different inlet flow angle and different inlet distorted velocity.

The input data are SITA1 : SKL : DL : Y(0) : DX : XL : ALFA(1,1): ALFA(2,1): ALFA(3,1): ALFA(4,1): ALFA(5,1): 2. 21) vertical extension of distorted flow at inlet δ(0 ) Δx , spatial increment along x direction L , ending position of x α ( 0 ) , x- direction velocity increment in the distorted inlet region at inlet β ( 0 ) , y- direction velocity increment in the distorted inlet region α 0 ( 0 ) , x- direction velocity increment in the undistorted inlet region β 0 ( 0 ) , y- direction velocity increment in the undistorted inlet region P(0), pressure at inlet kL Assumptions: Referential local flow directions relative to a stator and a rotor: SITAS=PSAIS=10 ( θ * = ψ * =100).
