About this deal

Although the onboard generation and storage of electrical energy is considered the primary obstacle to aircraft electrical propulsion, the distribution of electrical power and its conversion to propulsive thrust still present significant challenges. One of which is how to efficiently achieve propulsion for high-speed flight. WGU is keen to participate in this way and has made all of its published research on the FAST-Fan project freely available via the Wrexham Glyndwr University online research repository https://glyndwr.repository.guildhe.ac.uk/. Leave to cure for at least 24 hours, it can take up to 72 hours before it is completely safe to drive.

RIMSAVERS RIM PROTECTORS BY RIMBLADES® ARE DESIGNED TO ADD A PROTECTIVE TRIM RING TO THE OUTER EDGE OF ALLOY WHEELS TO ACT AS A BUFFER WHEN THAT INEVITABLE KERB DAMAGE DOES OCCUR AND OFFER OUR HIGHEST LEVEL OF PROTECTION ON FLAT WHEELS. At the heart of the FAST-Fan lies the energiser unit which transfers torque from the motors to the air via the fan blades. There is a finite rate at which energy can be transferred in this way, as governed by Euler’s Work Equation. The pressure rise across the fan is also important because it determines the achievable efflux velocity, which depends on the amount of energy (torque) that can be transferred per swept volume. The energiser unit is therefore optimised to deliver the required maximum amount of energy to the airflow, and the air is entrained in a duct of gradually decreasing volume to achieve the desired pressure rise over the dual fan stages. The closed fan-tips minimise pressure leakages and contra-rotation of the fans ensures that there is no energy lost in efflux swirl as the air flows through the nozzle to generate high-speed thrust. The relative rotor speeds can be independently modulated to control fan performance and in common with turbo-jet engines the FAST-Fan should benefit from ram-effect, especially whilst operating at high speeds and altitudes. Cooling-air enters from vents on the outer surface of the intake and is drawn over the motor windings by the motive flow of the exiting air. Start by pulling gently from the join. During removal, the core of the foam tape should split and half will be left on the rim surface. The aerodynamic fan blade profiles for modern aircraft are proprietary in nature and information is difficult to access. But such fan blades are often optimised to operate at super-sonic speeds such as 450 m/s, which is much higher than those anticipated for the FAST-Fan with sub-sonic operational air speeds closer to 200 m/s.Rimblades® Original are best suited to any rim with a rounded off top edge, but will fit any rim with a continuous surface. As they are rubber based they can cope with a varied range of rim edge profiles. In basic terms, Rimblades® Original are a C shaped profile.

Our DIY bonded products use a high quality double sided tape called a VHB (very high bond). This tape bonds to the wheel surface using viscous flow. This means the maximum bond is not instant, but takes around 72 hours to fully cure, although useable bond strength is reached within 24 hours. (Rimfinity are pro install only and do not require adhesives).

The rim blades also weren’t attractive as lots of people say they fling off and weren’t strong enough to take the hit. As the intention was to manufacture a prototype device. The dimensions of the FAST-Fan were determined by the available budget and prototyping machine capabilities. A 200mm fan diameter was selected based on initial calculations which also allowed a generous margin of up to 300mm diameter for designing and manufacturing the intake and nozzle. A novel manufacturing technique and bespoke tooling were developed to manufacture the bladed rotor assemblies.
