P2_6 It's the wrong trousers Gromit! Part 1

Abstract

In the classic film The Wrong Trousers Gromit receives some ex-NASA robotic Techno Trousers from Wallace for his birthday. This paper investigates whether the vacuum generator in the boots of the trousers would work when walking upside down on a ceiling as shown in the film. The vacuum generator required would need to be powerful enough to reduce the pressure in the boot by 18.5kPa. This suction is consistent with a low vacuum, and hence is feasible; however its operating time would be very short. Whether the trousers would work in space is also briefly discussed, concluding that it is unlikely with their current design.
