Hatcher Components are taking their commitment to reducing fuel costs on the road when they demonstrate their latest innovations in vehicle aerodynamics at the Commercial Vehicle Show at Birmingham NEC from 29th April-1st May 2014.
It is no understatement to say that the Commercial Vehicle Show is one of the biggest events in the UK transport and logistics calendar. It is here, in front of many senior industry figures, that the Hatcher Components team will demonstrate the fuel savings made possible by the use of their range of Air Management Spoilers, including the ‘Active Freddie’, which was developed in close conjunction with Cranfield University and Mercedes Benz UK. Hatcher’s range of innovative air management systems will be put through their paces in a special demonstration using a wind tunnel to highlight the benefits of the Active Freddie’s ‘3D Performance’ system.
The aerodynamic drag co-efficient of a moving vehicle has a considerable effect on fuel consumption, particularly when driving at motorway speeds. For a typical commercial vehicle travelling at a speed of 60 mph, roughly half the power of the engine is taken up overcoming the aerodynamic wind resistance. A major factor in this resistance is the shape of most goods vehicles, which is far from streamlined. This is due to the design of the vehicles being governed by other considerations such as ease of load handling, maximising vehicle load sizes within legal constraints, and ease of maintenance.
How ‘Active Freddie’ helps overcome these issues and delivers the fuel savings for which it has become so popular is down to the unique Freddie shape. Its ‘3D performance’ recognises the cross winds encountered in a typical journey and ensures that optimum performance is obtained over a much wider range of ‘yaw angles’ than is possible with a conventional static roof deflector. The ‘Active Freddie’ features manual, electric and auto-sensing adjustment options to trailer height, which ensures an aerodynamically optimised configuration between cab and trailer, with height-sensors advising the driver if they should make an incorrect adjustment. The Active Freddie recognises that the wind speed encountered by any vehicle is constantly changing, and pressure sensor monitoring whilst the vehicle is in motion allows the deflector to continuously optimise its position to the yaw angle, which provides consistent drag reduction and additional fuel saving of up to 5%, depending on cab and trailer shape.
Hatcher Components will be at Stand 4H50 of the Commercial Vehicle Show 2014 at the Birmingham NEC, from 29th April-1st May. As a taster for Hatcher Components’ demo at the CV Show, the benefits of the ‘Active Freddie’ spoiler can be seen in action in this video.
