Harold Whyman - Experimental Manager}23/ET.21.8.41. B.V CHASSIS - HEAT TO REAR SEAT. We have recently investigated a complaint by Sg.{Arthur F. Sidgreaves - MD}, that the N/S. rear seat on his B.V. car B.20.AW, became uncomfortably hot on a long run. We confirmed the complaint and found it was due to two reasons:- A - Exhaust tail pipe too close to the backboard of the rear seat squab. B - Poor fitting of the rear cushion in relation to the rear squab. We have overcome the trouble on this car by making a tunnel in the backboard so that there is a clearance between the backboard and the exhaust tail pipe, of 3.00". The rear cushion has been modified to fit closer up to the rear squab. In addition we have fitted a heat shield consisting of a sheet of asbestos clamped between two thin sheets of aluminium. The shield is in a position that allows a flow of air between the exhaust pipe and the shield, and between the shield and the body. We have checked up the clearance between the exhaust pipe and the backboard on a number of our cars, and they reveal anything but consistency. Herewith the cars and the respective clearances:- 12.B.V. 2.125" 8.B.V. 1.600" 10.B.V. 1.100" 1.RT.1. .625" 9.B.V. .125" 2.B.50 .125" Some of the discrepancy may be due to exhaust pipe distortion in service, or to inaccuracy in body manufacture, and we suggest that design should check the limits on chassis and body and arrange adequate clearance, the the fitting of a heat shield. | ||
