Streamlines: Automated Aerodynamic Drag Measurement in an Outdoor Environment

流线型为大众自行车市场带来骑手空气动力学优化。他们制造了两个小型装置，一个是空气动力学传感器，另一个是身体位置传感器。每个都可以简单地安装在自行车上，骑自行车的人可以在骑车时测量他们的空气动力阻力，并学习如何巧妙地改变身体位置来减少空气动力阻力。一般来说，超过60 - 90%的骑车者的能量是由空气阻力消耗的，而大部分阻力来自骑车者的位置，而不是自行车本身。空气动力学的改进使任何骑自行车的人都能更快、更远、更省力。目前，准确测量自行车手的空气阻力的唯一方法是在风洞或赛车场，这两种方法都很昂贵，即使是大多数自行车赛车手也无法承受，更不用说休闲自行车手了。流线型已经创建了一个精确的系统来测量空气动力学阻力和身体的位置在各种条件下的道路。流线公司使用了一种新型的空气动力学探针，由流线公司创始人约翰·巴克利共同发明。这个探头来源于一级方程式赛车的技术，但专门为自行车比赛中的湍流和风角而设计。将该探头与身体传感技术相结合，可在短短3分钟内实现精度为±1%的可重复测量。流线始终测量空气动力学阻力的自行车手在室外条件下，并已用于训练的奥运奖牌得主自行车手。该项目将简化用户与这项技术的交互，使其适用于日常骑行，同时扩大其对电动汽车和风能发电的适用性。

Streamlines is bringing rider aerodynamic optimisation to the mass cycling market. They have created two small devices, an aerodynamic and body position sensor. Each can simply attach to a bicycle and allow a cyclist to measure their aerodynamic drag as they ride and learn how they can subtly alter their body position to reduce their aerodynamic drag.Generally, over 60 - 90% of a cyclist's energy is consumed by aerodynamic drag, and most of this drag comes from the rider position, not the bicycle. Improvements to aerodynamics allow any cyclist to travel faster, further, and with less effort.Currently, the only way to accurately measure a cyclist's aerodynamic drag is in a wind tunnel or on a velodrome, both of which are expensive and out of reach for even most bike racers, let alone recreational cyclists. Streamlines has created an accurate system for measuring aerodynamic drag and body position on the road in a variety of conditions.Streamlines uses a new style of aerodynamic probe, co-invented by Streamlines founder John Buckley. This probe is derived from Formula One technology, but specifically designed for the turbulence and wind angles seen in cycling. Combining this probe with body sensing technology, repeatable measurements within an accuracy of ±1% can be achieved in as little as 3 minutes.Streamlines consistently measures aerodynamic drag for a cyclist in outdoor conditions and has been used in training by Olympic medal winning cyclists. This project will simplify a user's interaction with this technology so becomes suitable for everyday cycling while broadening its applicability to electric vehicles and wind energy generation.
