ABSTRACT:
Apparatus for measuring the flow area of a nozzle assembly is particularly applicable to structures such as jet engine nozzle assemblies or guide vane assemblies wherein a plurality of vanes or airfoil elements are supported in radially spaced apart relation, the apparatus including air moving means for supplying air through a first chamber, a second chamber, an air valve intermediate the chambers and the nozzle assembly. Measuring means are connected to each chamber to measure the respective air pressures. The apparatus can also include means for adjusting the size of the air valve opening between the two chambers as well as additional readout elements for facilitating the rapid and accurate measuring of the flow area of the nozzle assembly.
