The Small Business Innovation Research (SBIR) Phase I project will develop a Flexible Composite Surface Deturbulator (FCSD) tape and methods for affixing it to road vehicles to reduce air resistance. The FCSD is a thin, non-powered device consisting of a flexible membrane stretched across an array of strips on a substrate. The back of the substrate can then be bonded to the surfaces of a road vehicle. In the presence of a large turbulent wake (as evidenced by a large plume of spray when driving on wet highways), behind a road vehicle, the Deturbulator reduces drag by making the air stagnant in this virtual boat-tail. Even though about 80% drag reduction has been observed in wind tunnel tests, a detailed analysis of the flow-deturbulator interaction will be performed in order to optimize the Deturbulator for long distance trucks. The drag reduction achieved with a Deturbulator Tape will attract potential users in the U.S. and abroad to immediately retrofit and counteract increasing fuel prices. It will also help reduce emissions of toxic pollutants and greenhouse gases (CO2) from trucks and automobiles.

小型企业创新研究 (SBIR) 第一阶段项目将开发一种柔性复合表面扰流器 (FCSD) 胶带以及将其粘贴到道路车辆上以减少空气阻力的方法。 FCSD 是一种薄型、无动力设备，由在基板上的一系列条带上拉伸的柔性膜组成。 然后可以将基材的背面粘合到道路车辆的表面。在道路车辆后面存在较大的湍流尾流（如在潮湿的高速公路上行驶时产生的大量喷雾所证明的那样）的情况下，扰动器通过使空气停滞在这个虚拟的船尾中来减少阻力。 尽管在风洞测试中观察到阻力减少了约 80%，但仍将对流动与扰流器相互作用进行详细分析，以便优化长途卡车的扰流器。使用扰流器胶带实现的减阻将吸引美国和国外的潜在用户立即进行改造并抵消不断上涨的燃油价格。它还将有助于减少卡车和汽车有毒污染物和温室气体（CO2）的排放。
