INNOVATIVE CAR - 30/10/2019 - Communiqué de presse - Mission H24
MissionH24 achieved its end-of-season objectives. After its first entry for a race weekend at the Spa-Francorchamps circuit on 20th September, the hydrogen fuel cell-powered racing prototype LMPH2G was back in action on Friday and Saturday on the Portimão circuit, which hosted the last round of the 2019 Michelin Le Mans Cup.
In Portimão, the LMPH2G was in the same configuration as at Spa because the aim was to continue the validation of several technical solutions developed in private testing whose reliability still needed to be assessed.
On the programme of the H24Racing team, which operates the car, was, on the one hand to run the LMPH2G in the pack at high speed. And on the other, to enable the team to integrate itself into the racing environment, and in particular to continue its work with Total, which has designed a mobile station for refuelling in hydrogen specially for the MissionH24 project.
A new technological step in refuelling
For the first time, the car refuelled at the entry to the pit zone in the alignment of the other teams. Another first was that the Total engineers have now equipped their hydrogen refuelling station with an infrared link that connects the station to the car so that filling its tanks (temperature, pressure and quantity) is managed automatically. The only human intervention required during a refuelling stop for the LMPH2G is connecting the coupling connector and monitoring the automatic refuelling procedure to ensure that nothing goes wrong, then disconnecting the device.
Next week, H24Racing is going to continue its performance development programme so that after the first six months dedicated to validating new technical solutions, it will be in a position to restart its participation in racing weekends in 2020.
The figures of the two free practice sessions for the Michelin Le Mans Cup:
. 22 laps covered (13 for Norman Nato, 9 for Olivier Lombard);
. Fastest times: Friday 1m 53.966s, Saturday 1m 52.797s;
. 4 refuelling stops.
Olivier Lombard (driver of the no. 42 LMPH2G):
“Portimao is a difficult circuit because of its very varied layout – big differences in its gradients and slopes, its bumpy surface, sporadically high ambient temperatures and a fairly strong wind that regularly blew in gust. These particularities make it an excellent track for testing. So for us it was very important to run here during a race weekend to gather experience. We’re leaving with a great deal of data that will be full of rich information for the next stages of our development in the field of performance. I can’t wait to get behind the wheel again to continue our technical programme.”
Norman Nato (driver of the no. 42 LMPH2G):
“The two free practice sessions of the final round of the Michelin Le Mans Cup in which Olivier and I took part were worth their weight in gold! There was no question of driving at the maximum of our performance level or to push the car to its limits; that wasn’t our aim. As at Spa, our work plan was simple: measure ourselves against a difficult circuit, run in the middle of the pack do things at racing speeds both on the track, in the garage and during refuelling. At the end of the two days we have every reason to be very satisfied.”
