Quasi-Static Structural Analysis Of An Experimental Aircraft Wing, Scott Bender
Quasi-Static Structural Analysis Of An Experimental Aircraft Wing, Scott Bender
Doctoral Dissertations and Master's Theses
In this report, a quasi-static load analysis is conducted on an experimental light sport aircraft wing via a whiffletree bending test. This report will discuss the loads present on the aircraft during straight level flight at a speed of 82 knots equivalent air speed. Flight load calculations are described along with the design of the whiffletree and mounting structures utilized for applying the distributed point loads. Initial finite element analysis is performed on the wing structure to determine critical strain locations and optimal sensor distribution. Subsequent mechanical experimentations are performed using a bending test to measure the strain at critical …
Influence Of Wing Planform Shape On The Effectiveness Of A Fixed-Slot, Yuan Zhao
Influence Of Wing Planform Shape On The Effectiveness Of A Fixed-Slot, Yuan Zhao
Doctoral Dissertations and Master's Theses
This thesis report explores the effect of the Clark-Y wing geometry on lift and drag to use as a reference during aircraft design stage. The different characteristics investigated are fixed slot span, taper ratio, washout, and sweep angle. Plain wings, half slotted wings, and fully slotted wings were built in CATIA with an aspect ratio of 6 and different taper ratio, washout, and sweep angles. Using the CATIA models to generate the 3-D grids in Pointwise. All the simulations were tested in Ansys-Fluent under sea-level conditions with a Reynold number of 609000. The relationships between the aerodynamic characteristics and the …
