Optimal Design Operation Strategies of a Hyperloop Transportation System

In the last decades, transportation demand growth has played a major role in the increase of global CO2 footprint. At the same time, a number of countries have scheduled measurable and substantial cutback of CO2 emissions by 2050. As the transportation sec ...

Photogrammetric Mission Planner for RPAS

Jan Skaloud, Martin Rehak, Florian Gandor

This paper presents a development of an open-source flight planning tool for Remotely Piloted Aircraft Systems (RPAS) that is dedicated to high-precision photogrammetric mapping. This tool contains planning functions that are usually available in professio ...

ACTIVE MODEL ROCKET STABILIZATION VIA COLD GAS THRUSTERS

Gautier Marie Pierre Rouaze, Anton Ivanov, Xavier Collaud, Raimondo Pictet, Danylo Malyuta, Mikael Martins Gaspar

This paper describes the development and testing of a reaction control system (RCS) for a model rocket named FALCO-4. The rocket uses cold gas jets to keep itself perfectly vertical at low speeds. We first describe the mechanical layout of FALCO-4 and the ...

Modeling and Optimization of Terminal Airspace and Aircraft Arrival Subject To Weather Uncertainties

Maryam Kamgarpour, Wei Zhang

We develop an accurate model for the arrival traffic dynamics in terminal airspace that takes into account the weather forecast and runway configuration changes. The planning of runway configuration switching subject to weather constraints is formulated as ...

DRIE based novel technique for AFM probes fabrication

Luis Guillermo Villanueva Torrijo

We report on the fabrication of atomic force microscopy (AFM) probes using a novel technology that performs every machining step by means of one single deep reactive ion etching (DRIE) equipment. Specific etching conditions are optimized in order to define ...

Deep reactive ion etching and focused ion beam combination for nanotip fabrication

Luis Guillermo Villanueva Torrijo

We have studied the fabrication of high-aspect ratio silicon tips by a combination of deep reactive ion etching and focused ion beam. The reactive ion etching is used to obtain so-called "rocket tips" which can be fabricated with a high aspect ratio. The r ...
