TITLE Estimate Flutter Speed Half Wing Model of N219 using MSC NASTRAN |
 PDF |
ABSTRACT Flutter occurs when the aerodynamic forces associated with motion in two modes of vibration cause the modes to couple in an unfavourable manner. A half wing model was used to simplify the analysis and obtain its frequency and damping on a given speed range. This paper presents the prediction of flutter speed on half wing model N219 aircraft. This study covers two parameter variations, altitude (sea level, 5000 ft, 10000 ft) and Mach number (0.1; 0.2; 0.3). The model consists of three mass configurations: zero fuel, minimum fuel, and maximum fuel. The tools for flutter analysis in this research is MSC NASTRAN software. The most critical flutter speed occurred at 165 m/s, outside of flutter clearance envelope. |
