RE: PRESENTATION EVENING held at the MCRC Clubrooms Friday 13th October 2017
Over sixty members and supporters attended this presentation and information evening, the atmosphere was friendly and cordial. The WASCC General Manager Andrew Stachewicz made the presentation supported by the WASC President Russell Sewell.
Here is an overview
Working towards a return to Barbagallo… the last six months or so in brief.
A lot has been happening at Barbagallo Raceway since the meeting held at WASCC on May 25th, 2017. At this meeting - attended by the Minister for Sport, Mick Murray, Chris Hall of Hall Technical, representatives from MA, MWA, DSR, CoW, MCRCWA and WNOTB – the WASCC put forward a proposal for a staged return to motorcycle activity at the track.
The initial stages of this proposal involved finding a way to reduce the speed profile in certain areas of the circuit to reflect the speed suggestions in the Hall Report. The aim of stages one and two in the proposal was to enable rider training of the type provided by RidedaysWA and Trakdayz – levels one to three – to return to the circuit.
For Racing to continue further engineering assessment is required to address parts of the Hall Report, which Steve Brake is working on.
In early July a working group was established under the direction of WASCC. This group initially comprised of four accredited motorcycle coaches, a consultant engineer and members of WASCC. This was the earliest date that the consultant engineer, approved by MA, was available.
The fundamental aim of this group was to find a way to reduce speed in specific areas of the circuit using physical structures that in themselves did not create additional concerns. The areas identified requiring speed ‘modification’ were the exit of T1, the entry into T3, the exit of T5, the entry into T6 and the exit of T7. This was no simple challenge.
The process of identifying what would work, by way of apex-shifting ‘chicane’ modules, was tested at the circuit using members of the working group riding 600/1000cc motorcycles with cones (witch’s hats) placed at key locations and speeds recorded via a radar ‘gun’ and data logging from the bikes themselves. The working group was expanded to include another two riders – an A grade racer and a B grade racer/accredited coach.
Three full days, over a period of a month, of testing various layout options and assessing the resulting speed profiles/bike data enabled the consultant engineer to provide locations and sizes of the various modules required to achieve the aim.
Interestingly, the consultant engineer observed that the experiential feedback from the riders during these tests was essential. As an example, purely from an engineering perspective – placing a chicane on the exit of T5 seemed reasonable. The rider feedback concerning forward vision, camber and speed profile at that location made it very clear that this was not a good idea.
The ‘chicane modules’ themselves required a lot of consideration and design. They needed to be a temporary visual and physical change to the circuit that would not cause an issue if a motorcycle was to be ridden over them in error. The design was tested, on the wettest day imaginable, by one of the working group riding a motorcycle at speed across it, on the track, several times without issue.
The experiential feedback from the working group motorcyclists was that this solution was one that did not detract from the experience of riding Barbagallo as much as initially feared.
These modules have now all been fabricated and are ready to use and the engineering report – commissioned by WASCC – has been submitted to MA for consideration.
The report from Steve Brake was submitted to MA on Monday 9/10/17. MA came back Friday morning 13/10/17 with a couple of queries requesting the data, asking for the expected Air fence lengths and positions, to which the WASCC provided a response to straight away.
Works for January haven’t been fully planned yet, pending MA response, although the arrestor bed at Turn 5 will be added, as well as the tyres on the wall on the entry to 6 are to be removed, and the replacement wall will be 15-25m further back than the existing position.
WASCC confirmed that if any significant works are required, CAM’s won’t allow their license via the existing “grandfather clause” to continue, which means that other things would need to be addressed as well before it could be licensed again, hence why we are waiting for clarification from MA.
Now we wait for a reply from MA regarding the report and, hopefully, will be back on track soon.
