CFD Analysis of UAV Flying Wing
Journal Title: INCAS BULLETIN - Year 2016, Vol 8, Issue 3
Abstract
Numerical methods for solving equations describing the evolution of 3D fluid experienced a significant development closely related to the progress of information systems. Today, especially in the field of fluid mechanics, numerical simulations allow the study of gas-thermodynamic confirmed by experimental techniques in wind tunnel conditions and actual flight tests for modeling complex aircraft. The article shows a case of numerical analysis of the lifting surface on the UAV type flying wing.

Thrust and jet directional control using the Coanda effect
The application of the Coandă effect to the directional control of a jet or thrust is presented. Deviation of the thrust force by direct flow can be achieved by using the Coandă effect to change the angle of the primary...
About ideal relative motions of rigid heavy body
Consider an origin which is fixed at the Earth’s surface, and a rectangular celestial coordinates axes with this origin. The gravity acceleration is the approximate sum of the centrifugal acceleration of the origin relat...
Lightweight vitreous carbon material: approaches to making open-pore cellular structure
Cellular vitreous carbons with the open-pore structure are attractive materials in some aerospace applications, such as the super-lightweight structural materials or sandwich core materials in the thermal protection syst...
Earth – Mars Similarity Criteria for Martian Vehicles
In order to select the most efficient kind of a martian exploring vehicle, the similarity criteria are deduced from the equilibrium movement in the terrestrial and martian conditions. Different invariants have been obtai...
Definition and discussion of the intrinsic efficiency of winglets
Three simple equations are derived to define the “Intrinsic Aerodynamic Efficiency of Winglets” independent of the horizontal extension of the winglet and independent of the winglet’s (relative) height. This Intrinsic Ae...
