Measurements of the Motions of a Large Swept-Wing Airplane in Rough Air

Description: Note presenting flight test measurements of the angular and linear motions of a large swept-wing airplane in rough air for a range of altitudes. The measurements are summarized in the form of power spectra, root-mean-square values, and probability distributions. A procedure is given for extrapolating the measurements of the probability distributions and the power spectra to other turbulence conditions.

Effects of Airplane Flexibility on Wing Strains in Rough Air at 35,000 Feet as Determined by a Flight Investigation of a Large Swept-Wing Airplane

Description: A flight investigation was made on a large sweptback-wing bomber airplane and the results are compared with data previously obtained at low altitude (5,000 feet). The effects of wing flexibility on the wing strains were, on the average, about 20 percent larger at the higher altitude.

An Investigation of the Loads on the Vertical Tail of a Jet-Bomber Airplane Resulting From Flight Through Rough Air

Description: "Vertical-tail loads were measured in turbulent air on a four-engine jet bomber. Results showed large load oscillations which were lightly damped. Comparison of experimental results with discrete-load calculations indicated that discrete-gust calculations underestimated the loads by 30 to 40 percent and gave no indication of the low damping. Power spectral analysis, on the other hand, indicated the general frequency characteristics and gave a somewhat better estimate of the peak-load distributi… more

Effects of Airplane Flexibility on Wing Strains in Rough Air at 5,000 Feet as Determined by Flight Tests of a Large Swept-Wing Airplane

Description: Report presenting a flight investigation of a large swept-wing bomber airplane in rough air at 5,000 feet to determine the effects of wing flexibility on wing bending and shear strains. Aeroelastic effects were found to be large, particularly at the outboard measuring stations. Results regarding the bending strains and shear strains are provided.
