Abstract: The action of braking generates massive amounts of heat. It is known to install brake ducts (9), which channel air from the front of the vehicle to the brake discs (17). The air introduced by the brake ducts (9) is at an ambient temperature, much cooler than the brakes, and the airflow is closer to laminar (rather than turbulent) and continuously moves the hotter air away. This allows the brakes to shed heat at a faster rate and dramatically lowers the average operating temperature. The present invention provides a vortex tube (3) for supplying a stream of air (5) at a temperature substantially different from ambient temperature into brake ducts (9) to improve efficiency of the brake ducts (9).

Abstract: It is desirable to minimise all forms of trailing vortices from a moving vehicle, whether they are from turbulent form drag of a vehicle or from vortex drag. Wingtip vortices on aircraft can persist for relatively long times (of the order of several minutes after the passage of an aircraft) which can cause danger to other aircraft, in particular around airfields where time must be left between subsequent take-offs and/or landings on a given runway for such vortices to dissipate. According to a first aspect of the present invention, there is provided an active drag-reduction system having first (22) and second (24) fluid outlets located on a vehicle (10) adjacent to a low pressure (drag) region (12), wherein fluid ejected from the second fluid outlet (24) is at a higher pressure / ejection velocity than from the first fluid outlet (22). Turbulent and/or low pressure regions adjacent to vehicles are not uniform, but rather have a varying intensity. For instance, the centre of a region may have a lower pressure and/or more turbulent nature than the periphery of the region. In this way, therefore, the present invention allows the system of the present invention to inject relatively higher pressure air (or relatively higher speed air) into the relatively lower pressure / more turbulent part of the low pressure / turbulent region, and relatively lower pressure air (or relatively lower speed air) into the relatively higher pressure / less turbulent part of the low pressure / turbulent region, compared to each other.

Abstract translation: 理想的是使来自移动车辆的所有形式的尾流涡流最小化，无论它们来自车辆的湍流形式拖曳还是来自涡流阻力。 飞机上的翼尖涡流可以持续较长时间（飞机通过几分钟后），这可能对其他飞机造成危险，特别是在机场周围，在这些机场中，必须在后续起飞和/或着陆之间留出时间 在给定的跑道上这样的涡流消散。 根据本发明的第一方面，提供了一种主动减阻系统，其具有位于与低压（阻力）区域（12）相邻的车辆（10）上的第一（22）和第二（24）流体出口， 其中从所述第二流体出口（24）喷射的流体处于比来自所述第一流体出口（22）更高的压力/喷射速度。 与车辆相邻的湍流和/或低压区域不均匀，而是具有不同的强度。 例如，区域的中心可以具有比该区域的周边更低的压力和/或更湍动的性质。 因此，本发明因此以这种方式允许本发明的系统将相对较高压力的空气（或相对较高速度的空气）喷射到低压/湍流区域的相对较低的压力/更湍流的部分中，并且相对较低的压力 空气（或相对较低速度的空气）进入低压/湍流区域的相对较高压力/较低湍流部分，相互之间相比较。
