There are some situations where neither aquatic vehicles nor land vehicles can access certain locations

In these situations an amphibious vehicle that travels above the surface could reach these locations

Team 1: On Wings Like A Penguin


Project description
Project Description

  • Build an amphibious air cushion vehicle

  • Should seat two passengers

  • Two engines: one for thrust, another for lift

  • Approximately 12 x 6 ft, triangular shape

  • Lift engine will duct air into skirt using air splitters

Thrust propeller analysis
Thrust Propeller Analysis

  • Determined propeller tip speed would not exceed the speed of sound

  • Calculated craft drag forces and determined required propeller pitch

  • Calculated angle of attack along the propeller blade

Lift fan case study
Lift Fan Case Study

  • Designing a lift fan is an iterative process

  • Investigated three other functioning hovercrafts of similar size and weight

  • Determined lift engine specifications

  • Obtained general idea of lift fan dimensions
