Hi. Me and my team are re-building a human powered aircraft's transmission system, and are currently designing the part of the pulley and belt. We've bought the belt and pulley quite some time ago from different shops, thus, we now have to re-investigate whether the pulley and the belt match perfectly, and wish to investigate them in terms of efficiency and all the calculations involve, to ensure it can be performed at the best condition. All the details we have about them are merely the belt's code, which is "16T10/2800 PAZ Z045 408878" from BRECOFLEX company, and it was made in Germany. Does anyone able to give a hint on how can we find out more details and information about it, and how should we investigate it? Your advice and assistance will be very much appreciated. Thanks in advance!
