- Summary:
- An analysis of available theory on seaplane impact and a proposed modification thereto are presented. In previous methods the over-all momentum of the float and virtual mass has been assumed to remain constant during the impact but the present analysis shows that this velocity of the float is normal to the keel. The proposed modification chiefly involves consideration of the fact that forward velocity of the seaplane float causes momentum to be passed into the hydrodynamic downwash (an action that is the entire consideration in the case of the planing float) and consideration of the fact that, for an impact with trim, the rate of penetration is determined not only by the velocity component normal to the keel but also by the velocity component parallel to the keel, which tends to reduce the pentration.
