以前好像曾貼在玉山上, 不過玉山關門了.再貼一次也無妨. CF6-80E1A1:　　　　　　　　　Thrust, kN (lbf) Take-off (5 minutes):　　　281.539 (63290) Maximum Continuous:　　 258.096 (58020) CF6-80E1A2: Take-off (5 minutes):　　　287.055 (64530) Maximum Continuous:　　 268.683 (60400) CF6-80E1A3: Take-off (5 minutes):　　　304.848 (68530) Maximum Continuous:　　 268.683 (60400) CF6-80E1A4: Take-off (5 minutes):　　　297.465 (66870) Maximum Continuous:　　 268.683 (60400) CF6-80E1A4/B: Take-off (5 minutes):　　　304.848 (68530) Maximum Continuous:　　 268.683 (60400) ------------------------------------------------------ CF6-80E1A1: Basic model CF6-80E1A2: Same as CF6-80E1A1 except for higher Take off and Maximum Continuous thrust ratings. Corresponding Rating Plug changes. For CF6-80E1A2 engines with enhanced high pressure turbine (HPT) blades actual EGT redline is 1050 OC. Enhanced blades are defined as Stage 1 HPT blades with TBC and Stage 2 HPT blades of DSR 142 material. Engine rating and configuration are provided by the Rating Plug and Identification Plug, respectively. CF6-80E1A4: Same as CF6-80E1A2 except higher Take off thrust rating and actual EGT redline increased to 1045 OC. CF6-80E1A4 rating requires enhanced HPT Stage 1 and 2 blades and forged forward mount. CF6-80E1A4 engine actual EGT redline was increased to 1050 OC. ECU software and Identification Plug change only. Engine rating and configuration are provided by the Rating Plug and Identification Plug, respectively. CF6-80E1A3: Same as CF6-80E1A4 except higher thrust rating and actual EGT redline increased to 1060 OC. Includes the RD88 HPT and new Stage 1 low pressure turbine nozzle. Corresponding ECU software, Rating Plug and Identification Plug changes. CF6-80E1A4/B: Same as CF6-80E1A4 except CF6-80E1A3 Take off thrust rating available as a thrust bump feature. Maximum Continuous and Maximum Climb thrust are common. Corresponding ECU software, Rating Plug and Identification Plug changes.

Qatar 的A332 配置E1A4B 也是比華航更早發生類似事件. 之後,好像GE 對這兩款發動機的ECU (electronic control units )有所更改,聽說結果是導致推力比原有均略有下調. -- ※ 發信站: 批踢踢實業坊(ptt.cc) ◆ From: 78.32.116.233
