Prediction of the Rear Fuselage Temperature with Radiation Shield
In order to enhance the aircraft survivability, the infrared signatures emitted by hot engine parts should be determined exactly. For its reduction it is necessary for the rear fuselage temperature to be decreased. In this study, numerical modeling of flow fields and heat transfer characteristics of an aircraft nozzle is performed and its temperature distribution along each component wall is pr...
متن کاملNumerical and Experimental Investigation of Helicopter Fuselage Aerodynamics
The aerodynamic characteristics of an isolated MRH 90 helicopter fuselage have been investigated using Computational Fluid Dynamics (CFD). Simulations utilised an unstructured tetrahedral grid and both the k-ε and k-ω SST turbulence models were investigated. Standard ‘law of the wall’ wall functions were incorporated, along with a segregated finite volume solver. A wind tunnel testing program w...

متن کاملEfficient Aerodynamic Shape Optimization
Since the present author first became involved in computational fluid dynamics, around 1970, the landscape has changed dramatically. At that time, panel methods had just come into use, and the world’s fastest super computer, the Control data 6600, had only 131000 words of memory (about 1 megabyte). Prior to the break-through of Murman and Cole [1970], no viable algorithms for computing transoni...
متن کاملTopology and Parametric Optimization of a Lattice Composite Fuselage Structure
Conventional commercial aircraft fuselages use all-aluminium semi-monocoque structures where the skin carries the external loads, the internal fuselage pressurization and is strengthen using frames and stringers. Environmental and economic issues force aircraft designers to minimize weight and costs to keep air transport competitive and safe. But as metal designs have reached a high degree of p...
