Download or read book An Assessment of the Capability to Calculate Tilting Prop Rotor Aircraft Performance Loads and Stability written by National Aeronautics and Space Administration (NASA) and published by Createspace Independent Publishing Platform. This book was released on 2018-07-25 with total page 28 pages. Available in PDF, EPUB and Kindle. Book excerpt: Calculated performance, loads, and stability of the XV-15 tilt rotor research aircraft are compared with wind tunnel and flight measurements, to define the level of the current analytical capability for tilting prop rotor aircraft, and to define the requirements for additional experimental data and further analysis development. The correlation between calculated and measured behavior is generally good, although there are some significant discrepancies. Based on this correlation, the analysis is assessed overall as being adequate for the design, evaluation, and testing of tilting prop rotor aircraft. A general assessment of the state of the art of tilt rotor predictive capability is given. Specific areas are identified where improvements in the capability to calculate performance, loads, and stability are desirable. Requirements for more accurate and detailed data which support the development of improved analytical models are identified as well. Johnson, W.

This book was released on 2000 with total page 66 pages. Available in PDF, EPUB and Kindle. Book excerpt: Comparisons of measured and calculated aeromechanics behavior of a tiltrotor model are presented, with an emphasis on performance and structural loads. The recent test of the Tilt Rotor Aeroacoustic Model (TRAM) with a single, 1/4-scale V-22 rotor in the German-Dutch Wind Tunnel (DNW) provides an extensive set of aeroacoustic, performance, and structural loads data. The calculations were performed using the rotorcraft comprehensive analysis CAMRAD II. The comparison of measurements and calculations includes helicopter mode operation (performance, airloads, and blade structural loads), hover performance, and airplane mode performance. The correlation establishes the level of predictive capability achievable with current technology; identifies the limitations of the current aerodynamic, wake, and structural models of tiltrotors; and leads to recommendations for research to extend tiltrotor aeromechanics analysis capability.
