摘　　要：设置舰艏斜板以减少舰载机起飞滑跑距离、降低甲板风要求,从而实现无弹射系统情况下的短距起飞作业,这已在一些"蓝水"海军强国的航空母舰上得到了多年应用。给定航母起飞甲板长度和斜板曲线构型,飞机能否成功滑跃起飞取决于它的气动特性、最大起飞质量、发动机推力、出口速度和起落架强度。本文提出了一种舰载机斜板滑跃起飞情况地面载荷的计算方法,也建立了完整的斜板曲线方程(曲线已经过飞机适配性优化)。文中还应用本方法计算了某双座多用途舰载教练机的滑跃起飞地面载荷。Ramps have been used for many years aboard the carrier of some blue water naval powers to reduce take-off run distance and wind over deck（WOD） requirements, and to allow naval combat aircraft executing operations from carrier not equipped with catapults. Given particular ship deck length and ramp geometry, a given aircraft, which might or might not be able to successfully take off, will be depended on its aerodynamic characteristics maximum take-off weight（ MTOW）, engine＇s propulsion, exit velocity of aircraft and landing gear strength. The paper presents a general computing methodology of ground loads of carrier-based aircraft ski -jump take-off from carrier ramp, and establishes completed mathematical equations of ramp profile curve. The trajectory optimization of profile curve had been determined to be compatible with the aircraft. The proposed method is applied for analyzing the landing gear ground loads of a two-seat multi -role shipbome fighter ＆ trainer vis-à-vis its suitability for ski-jump take-off.
