TL;DR: In this article, the motion of the infinitesimal mass in the restricted three body problem is considered in the vicinity of the triangular solutions, when the more massive primary is regarded as an oblate spheroid with its equatorial plane coincident with the plane of the motion.
Abstract: The motion of the infinitesimal mass in the restricted three body problem is considered in the vicinity of the triangular solutions, when the more massive primary is regarded as an oblate spheroid with its equatorial plane coincident with the plane of the motion The effort here is to provide approximations to periodic solutions of finite size following the geometrical dynamic approach of Rand and Podogorski(1972)

TL;DR: In this article, the effect of shock train interaction with the intake shocks is focused to capture these phenomena, and it is demonstrated that the un-start mechanism is a continuous process with steady back pressures, whereas it is a discontinuous process under oscillatory back pressures.
Abstract: Experiments are carried out to characterize the un-start/re-start phenomena in an isolator with steady and low-frequency oscillatory back pressures (0.75 Hz–2.5 Hz) in Mach 1.7 flow. In the present study, the effect of shock train interaction with the intake shocks is focused to capture these phenomena. It is demonstrated that the un-start mechanism is a continuous process with steady back pressures, whereas it is a discontinuous process under oscillatory back pressures. The un-start mechanism is triggered once the oscillatory back pressure is above the maximum isolator pressure. As the frequency of back pressure oscillation is increased, the isolator experiences an early un-start and a delayed re-start. On the other hand, if the oscillatory back pressure is decreased, the re-start process is initiated. During the re-start process, the time lag is found to be increased, and the hysteresis loss is decreased with an increase in oscillatory frequencies. These phenomena are studied through both the steady and unsteady pressure measurements along with instantaneous schlieren images for different dynamic pressures. Furthermore, the un-start can be avoided or delayed by increasing the freestream dynamic pressure.

TL;DR: In this paper, the flatwise tensile strength (FTS), flatwise compressive strength (WCS), and edgewise CS were evaluated in terms of composite composite composites.
Abstract: Foam sandwich composites were processed using cyanate ester-based syntactic foam as core and carbon fabric-cyanate ester composite as skin. They were processed by a one-step compression-molding technique. The mechanical performance of the sandwich composites was evaluated in terms of flatwise tensile strength (FTS), flatwise compressive strength, and edgewise compressive strength. The dependency of these properties on the core composition was investigated. FTS initially increased with the increase in resin content of the syntactic foam core. However, higher resin content in the core led to a diminution in FTS due to high void content. The flatwise compressive strength and edgewise compressive strength and the corresponding moduli values showed an increasing trend with increase in resin content of the core despite the presence of voids at high resin content. The failure modes of the composites under different loading conditions have been examined. © 2008 Wiley Periodicals, Inc. J Appl Polym Sci, 2008
