چکیده

Abstract. This paper addresses the development of analysis tools for flight loads prediction in the pre-design stage. The analysis tools are embedded in a parametric modelling environment. Emphasis will be on prediction of aerodynamic loads on specific structural parts, like the fin, during dynamic manoeuvres. Principal requirement is that these loads can be computed with low effort, but with sufficient accuracy.

Solar Energy System Design of Ultralight Aircraft for Smoke Detection and Fire Alarm Proposes

Abstract: The purpose of this paper is to design and evaluate the construction of a lightweight solar aircraft that is capable of flying continuously for 24 hours relying solely on solar energy. The required energy is absorbed during the day by solar panels, some is used directly for flight, and the excess energy is stored in the aircraft battery for overnight flight. The aircraft will then be ...

In-Trim Flight Investigations of a Conceptual Fluidic Thrust-Vectored Unmanned Tail-Sitter Aircraft

The feasibility of using a stand alone Fluidic Thrust-Vectoring (FTV) system for the purpose of longitudinal trim of an unmanned aerial vehicle is the focus of the research presented in this paper. Since the fluidic thrust vectoring requires high pressure secondary air to deflect the engine exhaust gases, this research also provides an analytical toolset for preliminary sizing of a suitable sec...

Modeling, simulation and analysis of a multi degree of freedom aircraft wing model

This paper presented methods to determine the aerodynamic forces that acton an aircraft wing during flight. These methods are initially proposed for asimplified two degree-of-freedoms airfoil model and then are extensivelyapplied for a multi-degree-of-freedom airfoil system. Different airspeedconditions are considered in establishing such methods. The accuracy of thepresented methods is verifie...
