P2_4 Up, Up in the Atmosphere

Abstract

This paper is an investigation into the physical feasibility of Mary Poppins flying away using the lift generated on her umbrella from a natural wind source. The best case scenario used was adapted from the film such that the umbrella’s dimensions were greater and there was no drag force. A vertical wind speed of 37mph or a wind speed of 118mph at an inclination of 18.3°  would be required to lift a 60kg Mary Poppins off the ground. Taking into account that the pressure exerted would most likely destroy normal umbrellas, it was determined that materials with a greater tensile strength such as aluminium and polyester would be required to withstand the force of the wind.
