Experimental Investigations of an Oscillating Annular Compressor Cascade at Reverse Flow Conditions

While the advancement of computing hardware now enables accurate predictions of flutter and forced response at normal flow conditions during the compressor design phase, aeroelastic computations at off-design or reverse flow conditions remain a challenging ...

Vision-Based Navigation in Autonomous Close Proximity Operations Using Neural Networks

Seyed Mohammad Khansari Zadeh

Tight unmanned aerial vehicle (UAV) autonomous missions such as formation flight (FF) and aerial refueling (AR) require an active controller that works in conjunction with a precise sensor that is able to identify an in-front aircraft and to estimate its r ...

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 ...

Hybrid Optimal Control for Aircraft Trajectory Design with a Variable Sequence of Modes

Maryam Kamgarpour, John Lygeros

The problem of aircraft trajectory planning is formulated as a hybrid optimal control problem. The aircraft is modeled as a switched system, that is, a class of hybrid dynamical systems. The sequence of modes, the switching times, and the inputs for each m ...

Improved multi-aircraft ground trajectory prediction for air traffic control

John Lygeros, Ioannis Lymperopoulos

Accurate trajectory prediction plays a fundamental role in advanced air traffic control operations, because it forms the basis for (among others) conflict detection and resolution schemes. It has been demonstrated that improved trajectory prediction accura ...

Autonomous flight at low altitude using light sensors and little computational power

Dario Floreano, Jean-Christophe Zufferey, Antoine Beyeler

The ability to fly at low altitude while actively avoiding collisions with the terrain and objects such as trees and buildings is a great challenge for small unmanned aircraft. This paper builds on top of a control strategy called optiPilot whereby a serie ...

Autonomous flight at low altitude with vision-based collision avoidance and GPS-based path following

Dario Floreano, Jean-Christophe Zufferey, Antoine Beyeler

The ability to fly at low altitude while actively avoiding collisions with the terrain and other objects is a great challenge for small unmanned aircraft. This paper builds on top of a control strategy called optiPilot whereby a series of optic-flow detect ...

Benefits of Continuous Descent Operations in High-Density Terminal Airspace Considering Scheduling Constraints

Maryam Kamgarpour

This study estimates the potential benefits of continuous descents for more than 480,000 flights to 25 major airports in the National Airspace System. While reduced fuel consumption and greenhouse gas emissions are expected for these procedures, the benefi ...

In-situ observations of young contrails – overview and selected results from the CONCERT campaign

Julia Schmale, Roger Baumann

Lineshaped contrails were detected with the research aircraft Falcon during the CONCERT – CONtrail and Cirrus ExpeRimenT – campaign in October/November 2008. The Falcon was equipped with a set of instruments to measure the particle size distribution, shape ...

Application of Tactile Perception Enhancement

Sylvain Cardin

Surrounding environment is mainly perceived through sight and hearing. Our sense of touch is mostly dedicated to explore the surface of objects using hands and fingers. Tactile sensitivity of the body skin is rather limited in common life, however this rep ...
