Jet Blast Fence Investigation at John F. Kennedy International Airport.

摘要

A blast fence installed at the departure end of runway 31L at John F. Kennedy International Airport intended to protect aircraft landing on runway 4R from the effects of jet blast was believed to be ineffective. Tests were conducted in two phases. The initial phase was subjective, using smoke to aid in flow visualization. These tests were inconclusive and led to a second phase using instrumentation to determine whether or not a jet blast was present on runway 4R behind the blast fence. Results of phase II confirmed the presence of a jet blast. Tests covered seven aircraft types and indicated maximum blast velocities at runway 4R of 35 miles per hour above ambient wind.
