Trim Analysis of Box Wing Aircraft

Paul O Jemitola and Paul P Okonkwo
Abstract

Computational studies at the conceptual design level were performed to investigate the longitudinal trim of a Box wing aircraft. The analysis was intended to show the points in the envelope at which the aircraft could be trimmed longitudinally. A similar analysis was performed on an equivalent conventional cantilever aircraft. The results suggests that further optimization is required for the Box wing as its trimmable flight envelope is smaller than that of an equivalent conventional cantilever aircraft.

Interpretation of the Magnetic Measurements of the Swarm-A Satellite over Central Europe

PT Taylor, KI Kis, B Toronyi, S Puszta and G Wittmann
Abstract

Our paper discusses the determination of total magnetic field anomalies derived from the Swarm-A satellite data; one of two low orbiting satellites of the three Swarm formations. This procedure requires several modifications. The first step is the conversion of the measured CDF data to the ASCII format.

Aerospace Vehicle Systems Engineering and the Importance of Meteorology Inputs in Design

William W Vaughan and Dale L Johnson
Abstract

Aerospace Meteorology plays an important role in the design, development, and operation of aerospace vehicles. Many of the System Engineering issues and lessons presented herein occurred during the involvement of the authors with the development and interpretation of aerospace natural environment inputs, especially those of the terrestrial environment (0-90 km altitude).

Geometric Definition and Ideal Aerodynamic Performance of Parabolic Trailing-Edge Flaps

Douglas F Hunsaker, Jackson T Reid and James J Joo
Abstract

A parabolic trailing-edge flap is defined as a parabolic deflection of the airfoil geometry aft of a hinge point. Whereas a traditional flap deflection causes a discontinuous camber-line slope at the hinge point, a parabolic deflection produces a camber line that is first-order continuous at the hinge point. The geometry manipulation of a parabolic flap is mathematically defined such that it can be applied to any airfoil with a known camber line and thickness distribution.

Smooth-Wall Boundary Conditions for Energy-Dissipation Turbulence Models

DF Hunsaker, WF Phillips and RE Spall
Abstract

It is shown that the smooth-wall boundary conditions specified for commonly used dissipation-based turbulence models are mathematically incorrect. It is demonstrated that when these traditional wall boundary conditions are used, the resulting formulations allow either an infinite number of solutions or no solution. Furthermore, these solutions do not enforce energy conservation and they do not properly enforce the no-slip condition at a smooth surface.

Radial Turbine Performance Prediction and Design Optimization Whit Matlab Tool

A Leto
Abstract

The present work aims to show a methodology for estimating the compact radial turbine performance prediction for expander cycle rocket engine application, avoiding a detailed fluid dynamics analysis. The Radial Turbine Global Design RTGD code according to the type of fuel, hydrogen, methane or kerosene, determines the optimal velocity triangles, on the mean line, to minimize the overall dimensions, the losses, the flow rate and the pressure ratio, in order to maximize turbine performance for liquid rocket engine application.

Haptic Assisted Virtual Tele-Operation of Robotic Manipulator for Smooth Space Debris Capturing

Mutian Li and Xiutian Yan
Abstract

There are a number of challenges in space exploration missions and a growing challenge is the economic and efficient removal of space debris. A number of methods have been studied in literature to remove space debris which increase rapidly. This paper presents a novel method for capturing a targeted space debris in space using a robot with redundant degrees of freedom enabled with the assistance of haptic guidance.

Computational Aerodynamic Optimisation of a 2D Space-Shuttle Geometry

Thomas Chiles and Benjamin Evans
Abstract

The need for cost minimisation in astronautical engineering, to help make human kind an interplanetary species, is not just limited to the flight and manufacturing of spacecraft. Hypersonic aerodynamic optimisation has been an expensive and time-consuming necessity since the beginning of the Apollo missions.

Direct Ignition of a High Performance Hydrogen Peroxide Hybrid Rocket with 3-D Printed Fuel

Stephen A Whitmore
Abstract

Development of a high-performing hybrid rocket system that employs 90% hydrogen peroxide and 3-D printable thermoplastic materials is reported. Traditionally, high-grade peroxide has been employed as a monopropellant using noble-metal catalysts to initiate thermal decomposition. Catbeds beds are expensive, heavy, and contribute no propulsive mass to the system.
