16.2 Frontal test :
All parts which could materially affect the outcome of the test must be fitted to the test structure which must be solidly fixed to the trolley through its engine mounting points but not in such a way as to increase its impact resistance.
The fuel tank must be fitted and must be full of water. A dummy weighing at least 75kg must be fitted with safety belts described in Article 14.4 fastened.
However, with the safety belts unfastened, the dummy must be able to move forwards freely in the cockpit. The extinguishers, as described in Article 14.1 must also be fitted. For the purposes of this test, the total weight of the trolley and test structure shall be 780kg (+1%/-0) and the velocity of impact not less than 15 metres/second. The resistance of the test structure must be such that during the impact :
- the peak deceleration over the first 150mm of deformation does not exceed 10g ;
- the peak deceleration over the first 60kJ energy absorption does not exceed 20g ;
- the average deceleration of the trolley does not exceed 40g ;
- the peak deceleration in the chest of the dummy does not exceed 60g for more than a cumulative 3ms, this being the resultant of data from three axes.
My comments:
* 780 kg at 15 m/s has 87.75 kJ of energy.
* From 15 m/s to zero over one meter is an average 11.5 g.
* 10 g de-accelleration over 150 mm means going from 15 m/s to 14 m/s.
My interpretation is that doing away with more than 60 kJ (70%) of the energy before the "bump", is the trick here?
US F1 tells me it is on course to be in Bahrain - so ignore reports from Italy claiming it asked the FIA if it could skip the first races

TailEnders: http://www.jamesallenonf1.com/ - Gazetta reporting that US F1 may not be ready for 1st race. The 'reheat' feature isn't quite working yet!
Who is this "John Anderson" anyway, never heard of him actually, there's nothing on USF1 website either?marcush. wrote:with anderson joining USF1 to me it is fact not fiction that they will be on the grid from race 1 .
I guess i just ignore windsor.
