Following example of Russian carrier Admiral Kuznetsov shows the importance of wind on deck in STOBAR enabled vessels. The primary aircraft being used for the analysis is the conventional Su-33.The main data used for this analysis are:
Thrust to weight ratio of the aircraft (T/W) =0.89,
Radius of curvature of the curved flight deck(R m) = 180m;
which results in: Velocity of the aircraft towards the end of the curved deck; VII= 55.5 m/s;
Increase in angle of attack due to wind on deck effects;Δα=2.3o
The increase in aerodynamic force due to wind effects during flat deck run; (ΔF/F) = 66.3%
Hence, it can be inferred from the above example that wind on deck plays an important role for STOBAR configured vessels. Moreover, as discussed earlier ski-jump is preferred only for those aircraft having high thrust to weight ratio, to enable take-off solely through engine thrust. These constraints pose limitations to those aircraft having a low value of thrust to weight ratio.

.... 그니까 ....
Su-33 추중비가 0.89,
스키점프대 곡률이 180m일때
스키점프대 종단속도가 55.5m(108노트);
덱 이펙트(?)로 생긴 바람이 받음각 증가 ;Δα=2.3o
평갑판 활주할때 생긴 바람효과로 항공역학적 힘 증가 ; (ΔF/F) = 66.3%
볼드 부분 이해가 전혀 안가는데 헬프 좀...
갑판의 바람으로 인한 받음각차이가 2.3o 발생했다
평갑판 활주할때 생긴 바람효과로 항공역학적 힘 증가 ; (ΔF/F) = 66.3% -> 평갑판에서 바람불어서 항공역학적힘이 2/3 증가했다

오 땡큐땡큐
그리고 Radius of curvature of the curved flight deck(R m) = 180m; -> 스키점프대 곡률반지름이 180m 라는
ㅇㅇ 그건 이해함
곡률≠곡률반지름임요
그러니까 "스키점프대로 인해 받음각이 2.3도 커져서 맞바람효과가 66.3% 증가됐다?" 맞음?
아...
'커져서' 는 아니고 '커졌고, 그결과로' 가 맞을듯
ㅇㅇ; 땡큐 땡큐
곡률반지름.. 아.다른거구나
워서 갖꼬온겨??
인도 항모 연구 자료던데?
