Digital twin of the rotor-shaft of a lightweight electric motor during aerobatics loads

Robert Goraj

This paper aims to present airworthiness considerations regarding a shaft of an electric motor. A fatigue lifetime prediction analysis based on one-step load spectrum is performed…

Investigations of the vortex ring state on a helicopter main rotor using the URANS solver

Wienczyslaw Stalewski, Katarzyna Surmacz

This paper aims to present the novel methodology of computational simulation of a helicopter flight, developed especially to investigate the vortex ring state (VRS) – a dangerous…

Reactive flow simulations for a LOX/CH4 rocket engine

Ainslie French, Luigi Cutrone, Antonio Schettino, Marco Marini, Francesco Battista, Pasquale Natale

This paper aims to detail the reactive flow simulations of a LOX/CH4 multi-element rocket engine. The work has been conducted within the framework of the HYPROB-BREAD project…

Numerical prediction of vortex trajectories and vortex–blade interaction on the CROR engine

Nuno Vinha, David Vallespin, Eusebio Valero, Valentin de Pablo, Santiago Cuesta-Lopez

The exponential growth in computational capabilities and the increasing reliability of current simulation tools have fostered the use of computational fluid dynamics (CFD) in the…

Practical implementation of 4D-trajectories in air traffic management: system requirements and time windows monitoring

Álvaro Rodríguez-Sanz, Cecilia Claramunt Puchol, Javier A. Pérez-Castán, Fernando Gómez Comendador, Rosa M. Arnaldo Valdés

The current air traffic management (ATM) operational approach is changing; “time” is now integrated as an additional fourth dimension on trajectories. This notion will impose on…

Multicriteria decision-making in flight route selection

Leszek Rolka, Alicja Mieszkowicz-Rolka, Grzegorz Drupka

This paper aims to present a hybrid logical-arithmetic approach for selecting optimal flight routes. It can be used in the framework of free route airspace (FRA), which is aimed…

Modelling of the reference STARs procedures in the context of RPAS integration in non-segregated airspace

Daniel Lichoń

This work presents the part of the research in the integration of the remotely piloted aircraft systems (RPAS) in non-segregated airspace. The purpose of this study is to…

Flight reconfiguration system – an emergency system of the future

Piotr Grzybowski, Ewelina Szpakowska-Peas

This paper aims to describe the idea and partial result of research on flight reconfiguration system (FRS) which is to be used in case of pilot incapacitation while performing the…

The airplane trim system – new functionalities

Cezary Szczepanski, Mariusz Krawczyk, Albert Zajdel

A standard automatic flight control system – autopilot – will become required equipment of the future aircraft, operating in the common sky. For a specific group of aircraft, they…

Pilot-aircraft haptic feedback tests

Pavel Zikmund, Michaela Horpatzká, Lukáš Dubnický, Miroslav Macík, Ivo Jebáček

The purpose of this study is to lead to an improvement in pilot-aircraft interaction. The goal of the performed tests is an assessment of haptic feedback, which mediates flight…

CRW 13 – the new generation radio altimeter: the concept, design, and tests

Ewelina Szpakowska-Peas

The purpose of this paper is to outline a novel concept of radio altimeter CRW-13 that has been designed and developed in the Lukasiewicz Research Network – Institute of Aviation…

AESA radar and IRST against low observable threats

George-Konstantinos Gaitanakis, George Limnaios, Konstantinos Zikidis

Modern fighter aircraft using active electronically scanned array (AESA) fire control radars are able to detect and track targets at long ranges, in the order of 50 nautical miles…

Multiscale modeling of polymers filled with MWCNTs: the effect of dispersion, waviness, interphase and agglomerations

Panagiota Polydoropoulou, Konstantinos Tserpes, Spiros Pantelakis, Christos Katsiropoulos

The purpose of this paper is the development of a multiscale model which simulates the effect of the dispersion, the waviness, the interphase geometry as well as the…
