An Ameliorated Prediction of the Empennage In-Flight Gust Loads for a General Aviation Aircraft
… method for determining the fatigue life of an empennage based on the same normal acceleration data provided in AFS-120. However, this data have not been demonstrated to be applicable for empennage loads.</p> <p>Earlier works have shown that maneuver induced-loads on the empennage can be …

A Methodology for the Prediction of the Empennage In-Flight Loads of a General Aviation Aircraft Using Backpropagation Neural Networks
… from the maneuver in-flight loads in the empennage structure of a Cessna 172P. The purpose of this research was to develop a methodology for the prediction of strain in the tail section of a general aviation aircraft and to determine the minimum set of sensors necessary to adequately train …

Dynamics and Control of Flexible Aircraft
… of the flexible components (fuselage, wing and empennage), as well as the aerodynamic, propulsion, gravity and control forces. The aircraft motion is described in terms of three translations (forward motion, sideslip and plunge) and three rotations (roll, pitch and yaw) of a reference frame …

Flight Dynamic Constraints in Conceptual Aircraft Multidisciplinary Analysis and Design Optimization
… transonic transport aircraft, wherein the empennage assembly is optimized subject to both static constraints and closed-loop dynamic constraints. Under the relaxed static stability assumption, application of the VCFQ approach resulted in a 36% reduction in horizontal tail area and a 32% …

Conceptual design and multidisciplinary optimisation of power device for solar powered aircraft
… airfoil used for the wing design, while the empennage design, NACA 0008, was the most suitable. Hence, the latter was used for horizontal and vertical tail design with XFLR5 v6 software's aid. A novel methodology for the power device sizing was developed on MS Excel with 435.48Wh, 540.96Wh, …

Aero-servo-viscoelasticity theory: lifting surfaces, plates, velocity transients, flutter, and instability
… during flight such as interactions between the empennage and the aft fuselage, or control problems with the elevators. The research to discover the cause and correction of these undesirable characteristics formed the first foray into the field of aeroelasticity. Aeroelasticity is the …
