Review of hybrid composites fatigue

Anastasios Vassilopoulos, Dharun Vadugappatty Srinivasan

Hybrid composites become popular and are today used in a large number of contemporary structural applications. When compared to non-hybrid composites, hybridization offers additional benefits since the mixing of cheaper, low-quality fibers, with more expen ...

Optimal Thrust Vector Control of an Electric Small-Scale Rocket Prototype

Colin Neil Jones, Roland Schwan, Petr Listov

Recent advances in Model Predictive Control (MPC) algorithms and methodologies, combined with the surge of computational power of available embedded platforms, allows the use of real-time optimization-based control of fast mechatronic systems. This paper p ...

Modeling and experimentation of conductive and radiative transfer through heterogeneous insulators in high-flux environments

Jérémy Raphaël Mora-Monteros

Heterogeneous materials are used in a wide range of applications involving high heat flux environments such as concentrated solar reactors, high-temperature furnaces, or thermal protection systems of space vehicles. The thermal response of heterogeneous ma ...

The effects of radiation on ablative heat shields during atmospheric entry

Nikhil Banerji

Spacecraft employ composite materials as Thermal Protection Systems (TPS) to survive entering a planetary atmosphere at hypersonic speeds. Under intense convective and radiative heating from the surrounding shock layer, these composites decompose and erode ...

Tribocorrosion under fluid lubrication

Shoufan Cao

Wear is still the key problem causing the failure and limiting the lifetime of artificial hip joints, especially for the polymer acetabular cup in the metal-on-polymer and ceramic-on-polymer articulations. To reduce the wear, metal-on-metal articulation ha ...

A Drift-Kinetic Model for Tokamak SOL Plasmas

Paolo Ricci, Rogério Manuel Cabete De Jesus Jorge

A fluid drift-reduced description, which accurately describes phenomena occurring on time scales slower than the characteristic gyro-frequencies and space scales longer than the Larmor radii, has been successfully used in recent years to model the dynamics ...

Ground to Flight Investigations of Hayabusa with Ablation Effects

Pénélope Leyland, Daniel Potter, Nikhil Banerji, Jérémy Raphaël Mora-Monteros, Valentin Marguet, Elise Joy Fahy

Thermal protection systems (TPS) are of extreme importance for the survival of space vehicles especially during superorbital re-entry to Earth. The design of thermal protection systems requires in-depth knowledge of the thermal loading experienced during a ...

Coupling CFD and chemical kinetics: examples Fire II and TITAN aerocapture

Pénélope Leyland

The investigation of the thermochemical field around planetary reentry capsules, and their experimental scaled models is made by coupling aerothermodynamic simulation of the corresponding flow field to a library of chemical kinetics of the specific atmosph ...

Springer-Verlag New York, Ms Ingrid Cunningham, 175 Fifth Ave, New York, Ny 10010 Usa2009

The aim of this thesis is to assess the feasibility of integrating nanoparticles into glass fiber (GF) reinforced isotactic polypropylene (iPP) composites via existing thermoplastic processing routes, and to investigate whether this results in significant ...
