Abstract:
An inflatable drag reducer adapted to be mounted on the rear doors of a standard transport trailer, said drag reducer comprising a pair of flexible enclosed bags with one bag mounted onto each of the two trailer doors, said bags having a base surface adjacent to said trailer doors, said bags having adjacent medial surfaces, said bags having lateral, upper, and lower surfaces over which air passes during forward motion of said trailer, said bags containing an array of internal inelastic cords extending horizontally from the medial edge of said base surfaces to said lateral surfaces at equally spaced points, said bags containing a second array of internal inelastic cords extending vertically from said upper surfaces at equally spaced points to said lower surfaces at equally spaced points, such that upon inflation said drag reducer assumes a pyramidal shape with said lateral, upper and lower surfaces being substantially planar.
