| - 2 - do not consider the cotton makes an entirely satisfactory job. This R.{Sir Henry Royce} thinks also might be tested. In the case of the Bensport engine we have already fixed up a damper flywheel of the largest dimensions which it is possible to get in, and combined with a damper of the last mentioned type. This damper however, is enclosed and runs in oil, and is, therefore not suitable for test on the Peregrine which you have at the moment. We have issued an external dry damper flywheel for Japan 3 to drawing LeC.3091, and we have a scaled down replica of this for Peregrine. We propose to go over these designs with a view to increasing the inertia, and making the spring pressure conveniently adjustable, so that you can carry out the series of experiments for fixing the damper characteristics.
