Young Engineers & Greenpower Formula 24
Team Leader: John E. Davis
Foremarke Young Engineers and subsequently Greenpower Formula 24 started in November 2000 when we joined the ”Young Engineers Company Partnership Scheme”. This partnership included Staffordshire Setpoint and J C Bamford Excavators Ltd (JCB) who provided financial backing and personnel to help us achieve our goals. This partnership terminated in January 2006 due to JCB rationalising their support schemes for schools. Since then, the team has concentrated fully on building and developing race cars to take part in the national Greenpower Formula 24 electric car races for schools programme which sets out to inspire children at a relatively young age to be our future engineers. We remain members of the Young Engineers organisation.
The Foremarke Racing Team is made up from girls and boys in Years 7 and 8.
The team relies a great deal on corporate sponsorship to run this activity. Motor sport, even at this level, can be expensive and sponsorship, either financial or practical, enables us to continue to develop the cars and to design and build new ones so that we can compete effectively.
Race circuits we have recently competed at include:
- Goodwood Motor Circuit
- Silverstone Circuit
- Mallory Park Circuit
- Rockingham Speedway
- Croft Circuit
- Castle Coombe Circuit
We have had a total of five cars since 2005 but two have since been scrapped due to the ever changing race regulations making the required modifications impractical. In 2013 (post race season) we added another car and we anticipate completing the build of a new one for 2014. The cars still being actively raced are as follows:
FR-1 (2005) Our first car and it’s still going well. Originally a ‘Seagull’ kit from Greenpower this was constructed, with some modifications to the steering system, with an aluminium space frame chassis, carbon fibre floor and ABS body panelling. The following year major modifications were undertaken to the chassis profile to improve aerodynamics, battery location, motor cooling and single rear wheel drive system. Larger 16 inch diameter wheels were installed in place of the original 12 inch with disc brakes to the front along with rack and pinion steering. Over the years, various front end nose profiles have been used. This car has a single speed drive and is used as our ‘learner car’ for racing.
L: 2100mm W: 840mm (to hubs), 670 (body) H: 1008mm (roll hoop) Wt: 62kg
FR-2 (2008) Designed and built in house, this has a space frame chassis, carbon fibre floor and ABS body panels. The car has 20 inch diameter wheels with drum brakes to the front, rack and pinion steering and a Rohloff 14 speed gear driving a rear transaxle. This has been our most successful car over the years until the arrival of our latest car FR-5M in September 2012.
L: 2330mm W: 900mm (to hubs), 650 (body) H: 1060mm (roll hoop) Wt.: 71kg
FR-5M (2012) Using the ‘Trug’ type timber chassis modules, a rolling chassis was constructed with a single speed drive system. This car was intended to be much simplified from an engineering aspect from previous cars and to be aerodynamically superior. An aerodynamic body shell was designed in house to fit around the chassis and to be made out of either GRP or carbon fibre. Costs dictated that it would be GRP and we employed expert help in having the production moulding tool made and subsequent two part body shell made. 16 inch wheels are used all around with drum brakes on the rear pair. Only the rear wheels are fully enclosed within the bodyshell. A soft start motor controller is built into the power system to aid race starts. This performance of this car is a 20% improvement on that of FR-2.
L: 2700mm W: 780mm H: 810 (roll hoop) Wt: 54kg
FR-6M (2013) Another ‘Trug’ type chassis similar to FR-5M but with a moulded ‘foam’ body shell that saves considerable weight. Component parts are similar to FR-5M but has an inboard drive system instead to improve aerodynamic efficiency. This car has superior aerodynamics compared to any of our previous cars and early testing has shown a significant step up in performance. This was borne out in its first race season during 2014 where it has so far gained two wins and four second places and we have high hopes for the 2014 National Final.
L: 2800mm W: 730mm (hubs) H: 810mm (roll hoop) Wt: 35kg
FR-7K (2015) This is the newest car and is based on the Greenpower standard ‘Kit Car’ chassis. FR-7K competes in the F24 racers with our other cars but allows us to take part in the separate Kit Car class at each event. Assembled by a group of our year 7 pupils FR-7K is in its second season of racing and is regularly achieving podium finishes.
FR-8 (2017)– This will be our new car which is the very early stages of design. The car is to be built as much as possible ‘in house’ and will have a modular construction featuring interchangeable: steering, drive mechanism and driver compartment to allow for performance modifications and to take into account any future rule changes. The car will also feature more advanced electronics for better speed control and to maximise battery life during racing.
