Abstract: A plenum of distributing a flow of air from an air source includes ports extending from a face element of a body. The ports are configured to direct the flow of air out of the plenum, and the ports are arranged on the face element in a first row having first length, a second row having a second length, and a third row having a third length. The first row is positioned proximate to the top element, the third row is positioned proximate to the bottom element, and the second row is positioned between the first row and the third row. In addition, the second length is greater than the first length and the third length, and a shape of the face element is configured to accommodate the first length of the first row, the second length of the second row, and the third length of the third row.

Abstract: Technologies are generally described for multi-resolution based power spectral density estimation. According to some examples, a first power spectral density (PSD) of a signal may be computed to determine a first frequency resolution and a first error variance (EV) value associated with the PSD. The first PSD may be computed using fewer segments of the signal to achieve a higher resolution. The higher resolution is associated with a higher EV because of the fewer segments used for the computation of the first PSD. Next, a second PSD may be computed using the signal while sampling more segments to determine second resolution and EV. The second PSD may be associated with a lower EV because of the additional segments used for the computing of the second PSD. Missing frequency variables of the second PSD may be determined using the first resolution and the second EV through an expectation maximization technique.

Abstract: A check calibration device for a sting-held strain-gauge wind tunnel balance to permit pre-test or inter-test checking of the calibration of the balance in a short time is provided. The device comprises a housing adapted to be secured rigidly to the sting. A plurality of actuators are secured to the housing. Each actuator is positioned to act to generate a force in a predetermined direction at a predetermined location on the body of the balance when the balance and housing are in position secured to the sting. The device further comprises means to vary the load force applied by each actuator. Means are also provided to determine the load force applied by each actuator at a particular point in time and to measure the behavior of the balance in response to that load force at that point in time.
