Ferrari 248 F1 - revised front wing

　　法拉利248F1－改进后的前定风翼

　　Ferrari's front wing was the subject of much discussion at the last round in Malaysia. Onboard TV shots showed the upper profile bending downwards at speed, opening up a gap between the wing element and the nose cone, prompting many to question whether this constituted a moveable - and hence illegal - aerodynamic device. In theory this design should help push back the car's centre of aerodynamic pressure. This means the rear would run closer to the ground, increasing the available downforce created by air passing underneath. Furthermore, the front end would become slightly more understeery - and hence controllable - at high speed. Such principles are no huge secret, but only the top teams are likely to find ways of designing structures that may flex at high speed, but still pass the relevant FIA tests. Nothing illegal was found on Ferrari's car at Sepang, but for Melbourne reinforcements have been applied where the upper wing profile meets the nose (see detail), making for a more rigid connection.

　　在上一站马来西亚的比赛中，法拉利的前定风翼是众多争论的焦点。车载电视镜头的画面显示，上层风翼在高速状态下向下弯曲，风翼和鼻锥之间就会出现了一个缺口，因此很多人都怀疑，这是不是已经构成了可移动的空气动力学部件，因此属于违规的。在理论上，这个设计有利于将赛车的气动压力中心往后推移。这意味着赛车的尾部可以更加贴近地面，增加了赛车底部气流通过时所产生的可用下压力。此外，前端可能会稍微有点转向不足，因此在高速状态更容易控制一些。这些原理并不是什么大不了的秘密，不过只有顶级车队才能力设计出这种既能在高速状态下发生形变，又能通过国际汽联相关检测的结构。在雪邦，法拉利的赛车完全符合规定，不过在墨尔本，（赛车）采取了加固措施，上层风翼直接连到了鼻翼上（见详图），这样就使连接的刚度增加了。

　　宝马索伯F1.06－前定风翼端板

　　For Melbourne, the team introduced a revision to the front wing design seen in Bahrain and Malaysia. The main profile is largely unchanged, but the endplates now feature an upward-curving fin (yellow and detail), which closely resembles the one adopted on last season's Sauber. This fin reduces turbulence and hence improves the airflow passing close to the front wheels. This solution is likely to be alternated with the original flat fin over the course of the season, depending on how tight and twisty the circuit. The small change may provide an overall aero efficiency gain of around three percent.

　　在墨尔本，（宝马索伯）车队将曾在巴林和马来西亚使用过的前定风翼设计进行了修改。主型面没有大的改动，不过现在的端板多了一个向上弯曲的鳍翼（图中的黄色部分），非常类似于上个赛季索伯赛车上的部件。在本赛季的比赛过程中，这一方案很可能会同原来的扁平鳍翼一起轮流使用。这个小小的变化大概可以让整体空气动力学效率增加百分之三左右。
