Blast Reinforcing of Unit Load Device Using High Modulus Polypropylene Plain Weave Fabrics

S Kilimtzidis, A Kotzakolios and V Kostopoulos
Abstract

The present study investigates whether lightweight fabrics can be used for reinforcing the Unit Load Device (ULD) of a commercial aircraft, protecting them from potential bomb threats or explosives. As a first step, a numerical model of the fabric was developed and introduced to LS-Dyna for modeling a low-velocity impact event and the results were compared against conducted corresponding experiments, in order to validate the fabric properties concluded by the analysis.

Origin and Physical Properties of the Black Hole

Sergey Orlov
Abstract

A new physical model is proposed for the appearance of an astronomical object-the Black Hole. It is shown that the Black Hole is the center of the cosmic, etheric, gravitational torsion. An equation for determining the radius of this object based on the theory of vortex gravity is presented. A substantiation is proposed that the force of gravity on the surface of the Black Hole does not depend on the mass of this Black Hole.

A Predictive Solution for Engineering Calculations on a Full Scale Aircraft Post-Crash Fire

HY Wang and GD Wang
Abstract

Large Eddy Simulation combined with an Eddy Dissipation Concept (EDC) combustion model shows the feasibility for simulations of a full scale aircraft immersed within a large aviation-fuel fire in a moving fluid medium. Coupling between the condensed fuel and gas phases allows investigating the roles of the wind condition on the burning rate of condensed fuel, and consequently, the heat release rate. The prediction indicates that interaction between aircraft and fire environment combined with the influence of wind conditions (speed and direction) affects dramatically dispersion of the smoke products, such as carbon monoxide and soot.

Preliminary Design of a Generalized Vestibular Sensory System

Hooshang Hemami and Kamran Barin
Abstract

A rudimentary vestibular system as a single sensory system for a multi-rigid body system is proposed. The semi-circular canals represent the main sensors for the state of the physical system, and are modeled as accelerometers. Their outputs are used to estimate the angular velocities and positions of the multi-rigid body system. The states and the accelerations are utilized in feedback and feed forward control paths for movements on the ground and in the air.

Advantages of Using Additive Manufacturing to Build "Green" Fuels for Hybrid Propulsion

Stephen A Whitmore
Abstract

Advantages achieved by 3-D printing of hybrid rocket fuels are presented. This approach overcomes multiple manufacturing issues frequently associated with hybrid rockets including low fuel regression rates and poor ignitability. Using 3-D printing also allows fabrication of fuel grains with port shapes that enhance burn properties and increase volumetric efficiency. Printing ABS creates small, micron-thick features that provide surface arc paths allowing fuel pyrolysis at moderate voltages.
