Nonlinear Modal Analysis of a Full-Scale Aircraft [PDF]

open access: yesJournal of Aircraft, 2013
Nonlinear normal modes, which are defined as a nonlinear extension of the concept of linear normal modes, are a rigorous tool for nonlinear modal analysis. The objective of this paper is to demonstrate that the computation of nonlinear normal modes and of their oscillation frequencies can now be achieved for complex, real-world aerospace structures ...

Airframe Noise Simulations of a Full-Scale Aircraft [PDF]

open access: yes2018 AIAA/CEAS Aeroacoustics Conference, 2018
Computational results for a full-scale simulation of a Gulfstream G-III aircraft are presented. In support of a NASA airframe noise flight test campaign, Exa Corporation’s lattice Boltzmann PowerFLOW® solver was used to perform time-accurate simulations of the flow around a highly detailed, full-scale aircraft model.

Research on high attack angle stall and spin characteristics with flight test of a general electric aircraft

open access: yesXibei Gongye Daxue Xuebao, 2021
When the aircraft is flying at high angle of attack, the local separation of the air flow on the surface of the aircraft, the linear change of aerodynamic force is destroyed, and the maneuverability and stability are reduced to varying degrees, resulting

Generating Methods of Severe Load Spectra for Airplanes Based on Statistic Analysis in Flight Subjects

open access: yesHangkong gongcheng jinzhan, 2019
Nowadays, the mean load spectra is mostly used in fatigue test for aircraft, but it has the defects of long fatigue cycle. The severe load spectra is used instead, which can shorten the test time greatly. In order to meet the demand of full-scale fatigue
