We investigate numerically the transient forces produced by an air-in-liquid compound drop
impacting onto a solid surface. We demonstrate that the presence of a bubble in the drop
decreases the impact force. This decrease can be mainly explained by a reduced area over
which the impact pressure is applied. We systematically vary the bubble size to understand
its effect on the maximum normal force. A simple scaling model for the maximum impact
force is developed to accommodate the effect of bubble size.
