Introduction A transient pulse technique is used to The calculationof aeroelastic response in " obtain harmonic forces from a time-marching the transonic regime continues to be an active solution of the complete unsteady transonic area of research because of the significanceof small perturbation potential equation. The flutter in this speed range. Finite-difference unsteady pressures and forces...

The objective of this study was to develop and evaluate the Polish digit triplet test for speech intelligibility screening. The first stage of the work deals with the preparation of the test and the recording procedure. The second part presents results of the digit triplets intelligibility measurement and retest data. The test consists of 4 statistically equivalent and phonemically balanced lis...

This study compares, for listeners with normal hearing and listeners with hearing loss, the recognition performances obtained with digit-pair and digit-triplet stimulus sets presented in multitalker babble. Digits 1 through 10 (excluding 7) were mixed in approximately 1,000 ms segments of babble from 4 to -20 dB signal-to-babble (S/B) ratios, concatenated to form the pairs and triplets, and rec...

At transitional Reynolds numbers 104 − 105 , many smooth airfoils experience laminar flow separation and possible turbulent reattachment, where the occurrence of either state is strongly influenced by small changes in the surrounding environment. TheEppler 387 airfoil is one ofmany airfoils that can havemultiple lift and drag states at a single wing incidence angle. Prestall hysteresis and abru...

The Reynolds-averaged Navier–Stokes equation for compressible flow over supercritical airfoils under various conditions must be rapidly and accurately solved to shorten design cycles such airfoils. Although deep-learning methods can effectively predict fields, the accuracy of these predictions near sensitive regions their generalizability large-scale datasets in engineering applications enhance...

An experimental study was conducted to investigate the aerodynamic characteristics of a bioinspired corrugated airfoil compared with a smooth-surfaced airfoil and a flat plate at the chord Reynolds number of ReC = 58,000–125,000 to explore the potential applications of such bio-inspired corrugated airfoils for micro air vehicle designs. In addition to measuring the aerodynamic lift and drag for...
