TL;DR: In this paper, the standard tensile tests were conducted following ASTM Standards D3039 (Standard Test Method for Tensile Properties of Polymer Matrix Composite Materials) and D3518 (standard test method for In-Plane Shear Response of PolyMER Matrix Composite materials by Tensile Test of a ±45° Laminate), on non-hybrid plain weave composite materials.
Abstract: Monotonic tensile tests were conducted following ASTM Standards D3039 (Standard Test Method for Tensile Properties of Polymer Matrix Composite Materials) and D3518 (Standard Test Method for In-Plane Shear Response of Polymer Matrix Composite Materials by Tensile Test of a ±45° Laminate), on non-hybrid plain weave composite materials. Strips (6.35mm×25mm×250mm) of non-hybrid IM-7 Graphite/SC-79 epoxy called GR for short, non-hybrid S-2 Glass/SC-79 epoxy called GL for short specimens were tensile tested. The tests were conducted at -60°C, -20°C, 75°C and 125°C. The Poisson’s ratios were measured using strain gages. It was observed that temperature had a small effect on the Poisson’s ratio.

TL;DR: In this article, a two-dimensional model of surface dielectric barrier discharging (SDBD) in atmospheric N2-O2 mixtures was proposed, where the coupling theory between plasma aerodynamic actuation and fluid flow was studied.
Abstract: It is an important issue to study the mechanism of surface dielectric barrier discharging(SDBD) in atmospheric N2-O2 mixtures when the coupling theory between plasma aerodynamic actuation and fluid flow is studied.Thus,coupling chemical reaction kinetic equations of the plasma with the drift-diffusion fluid equations which consider energy equilibrium,we put forward a two-dimensional model of SDBD in atmospheric N2-O2 mixture.Then,taking 15 species,35 chemical reactions and corresponding electron impact reactions into account,we obtained the VA characteristics,electron charge distribution,and electron energy distribution of SDBD.The results show that the impact of hot electron is the main source of ions,meanwhile,accumulation of low energy electrons on anode and the motion of ions driven by the electric field are important reasons of the non-equilibrium in the SDBD.The calculation results are compared with the VA characteristics,discharging profile,and spectrum analysis results obtained by experiments,and their consistence validates the correctness of the proposed model.

TL;DR: In this paper, results from low-speed windtunnel tests on an isolated generic chined forebody with pneumatic methods of yaw control at high alpha were presented.
Abstract: Abstract Results are presented from low-speed windtunnel tests on an isolated generic chined forebody with pneumatic methods of yaw control at high alpha. Measurements of forces and moments were made on the forebody at angles of attack in the range 0° ≤ ɑ ≤ 60°. Slot blowing through the chine edge at various angles and upper surface tangential blowing have been compared, and optimum configurations have been identified. The effects of forebody cross-sectional shape have also been investigated and have been found to be highly critical in determining blowing effectiveness. Limited flowfield visualisation is also presented in order to gain some understanding of the flow field characteristics.

TL;DR: Guderley, Armitage and Valentine as discussed by the authors computed the inlet and closed body contours which form the forepart of an axially symmetric body, of given length and fineness ratio, having minimum pressure drag.
Abstract: Guderley, Armitage and Valentine have computed the inlet and closed body contours which form the forepart of an axially symmetric body, of given length and fineness ratio, having minimum pressure drag. The solution is not based on a simplified pressure law, such as the Newtonian impact law, because by a suitable choice of control surface for mass flow and momentum they are able to employ the general flow equations. It is clear, however, from an analysis of their tabulated results that their cowl shapes fall on a single curve for a given value of Δ= d i d t , the ratio of the initial to the final diameter of the cowl, when plotted in terms of a dimensionless length ξ= x/l and thickness η= y/d t , as in Fig. 1. Furthermore Fig. 1 shows that, except for small values of Δ, the Guderley shapes are indistinguishable from the optimum shapes calculated from Newtonian impact theory. The shape and characteristics of the Newtonian duct of given length and thickness, offering minimum drag to the external stream, are derived using the slender-body approximation. Ducts for which Δ > 0.04 are shown to be sufficiently slender. The slopes of those with 0 ≤ Δ
