It was proposed that an open- or closed-jet variable pressure water tunnel with an air-bubble resorber be constructed at the David Taylor Model Basin at Carderock, Maryland. This tunnel initially was to have a 36-in. diameter, cylindrical, closed-jet test section about 6.5 ft long and an alternate 36-in. diameter open-jet test section diverging to a 38.25-in. diameter
over a length of 4.8 ft. These test sections were to be followed by a 7° conical diffuser, a vaned elbow, a second diffuser, a second elbow, the pump, a third 9° diffuser, a third elbow, an air-bubble resorber 25 ft in diameter and 70 ft high, a fourth vaned elbow, a honeycomb, and a 9-to-l contraction section *. A tapered closed-jet test section was later considered.
