Presentation Title: LCA Applications and Benefits in Airport Premises

LCA Applications and Benefits in Airport Premises

Life Cycle Assessment (LCA) is an essential tool for evaluating the environmental effects associated with the entire life cycle of products and services, including those found in airport operations. By analyzing inputs, outputs, and potential environmental effects, LCA helps decision-makers identify significant environmental concerns and make informed choices among various alternatives. In airport premises, LCA can be applied for energy used and infrastructure areas to enhance sustainability and reduce ecological footprints. Airports are energy-intensive facilities, and LCA can help assess the energy consumption patterns associated with various operations, from terminal buildings to ground support equipment. By identifying high-energy processes, airports can implement energy efficiency measures, explore renewable energy sources, and optimize energy management strategies. The construction and maintenance of airport infrastructure, including runways, taxiways, and terminals, have substantial environmental effects. LCA can evaluate the materials used.

Presentation Title: Probabilistic-Adaptive Kalman Filtering for Fault-Tolerant Estimation of UAV States

Probabilistic-Adaptive Kalman Filtering for Fault-Tolerant Estimation of UAV States 

A probabilistic-adaptive Kalman filter (pAKF) algorithm for the fault tolerant estimation of unmanned aerial vehicles (UAV) dynamics in the presence of measurement faults is proposed. The proposed pAKF based on the evaluation of the posterior probability of the normal operation of the system, given for the current measurement. This probability is proposed to calculate via the posterior probability density of the normalized innovation sequence at the current estimation step. As a result, faults in the estimation system are corrected by the system, without affecting the good estimation behaviour. The pAKF algorithm is used for fault-tolerant estimation of UAV dynamics. The proposed pAKF is tested for the different measurement malfunction scenarios.

Presentation Title: Further aspects in the development of a proton exchange membrane fuel cell light aircraft

Further aspects in the development of a proton exchange membrane fuel cell light aircraft

In previous work, some initial thoughts on the possibility of using a stack of individual proton exchange membrane fuel cells to power an existing light aircraft were presented. This stack liberates the energy contained within cryogenically stored hydrogen enabling electricity to carry the energy via a boost controller to a permanent magnet synchronous motor to drive the propeller. In this work we discuss the layout of the new power train on the location of the aircraft’s centerof-gravity and its movement. We discuss the impact of the fuel cell stack’s thermal efficiency on the amount of heat that needs to be rejected and how this might be achieved on a light aircraft. We will discuss the possibility of using a battery pack when climbing/maneuvering to minimize heat transfer. We consider ways in which the fuel cell stack, battery pack, boost controller, permanent magnet synchronous motor, and variable pitch propeller work together to maximize efficiency while making the power available to match the power required in different flight scenarios.

John Olsen obtained a PhD from the University of Newcastle, Australia in 2001 for his work on the control of turbulence in jet flows.

Capacity-building academic activities for the first scientific Serbian nano satellite MOSAIC

The institutional space investigation in Serbia dates back to 1887 when the Astronomical Observatory was founded. Since then, space science, encompassing investigations in astronomy and astrophysics, has been developed. However, research and development in space technology began only a few years ago, primarily through a CubeSat project called MOSAIC. This will be Serbia’s first scientific satellite and will be used primarily to observe X-ray radiation from the Sun. This initiative led to the establishment of a Research Unit for space science and technology at the Astronomical Observatory. The unit is tasked with advancing academic activities related to space science and technology in Serbia and identifying local capabilities for developing space technology in collaboration with relevant academic institutions and private companies. We will present possibilities and opportunities for future work in this field.


In this context, we will also present the first activities of the MOSAIC mission. We will discuss the mission specifications and requirements, as well as the first steps taken so far. The CubeSat is planned for launch in 2026. We will also present an investigation of space flight, orbital parameters, and sustainable orbit during the maximum of the Sun’s activity for this mission.

Presentation Title: The Conceptual Design, Analysis and Optimization of a Hydrogen Combustion Powered Aircraft

The Conceptual Design, Analysis and Optimization of a Hydrogen Combustion Powered Aircraft

In the effort to combat climate change worldwide, the aviation industry faces particularly complex design challenges in designing new, emission free vehicles. One potential solution to this problem is the use of hydrogen fuel as a means of propulsion. Hydrogen fuel has many benefits over traditional jet fuel such as a higher gravimetric energy density; however, it requires the aircraft to carry large, pressurized, cryogenic fuel tanks. This paper examines the design challenges, potential solutions, and the analysis methods for the design of a short to medium range hydrogen powered commercial airliner. To accomplish this goal, a comprehensive conceptual design and analysis code called WUADS (Washington University Aircraft Design Software) is developed. WUADS employs a combination of empirical and numerical methods to analyze an arbitrarily input aircraft’s overall weight, propulsive efficiency, and aerodynamic performance. This code is first validated on several existing aircraft to verify the accuracy of the analysis and optimization methodology of WUADS, then it is used to analyze several configurations of hydrogen powered aircraft. The first hydrogen powered configuration tested is a medium range airliner based on the performance metric of the Boeing 737-800, which makes use of propulsion through direct hydrogen combustion. The Preliminary analysis shows that the optimal placement of the required cryogenic hydrogen fuel tanks is inside the fuselage. With this knowledge, a hydrogen powered aircraft configuration is designed and optimized with an extended fuselage to fit the fuel tanks. This configuration demonstrates a clear increase in efficiency over the Boeing 737-800. The same analysis is conducted to design a hydrogen powered Boeing 767 with internal hydrogen fuel tanks.

Presentation Title: Certification Challenges for New Generation Sustainable Aircraft

Certification Challenges for New Generation Sustainable Aircraft

There and more than 200 different initiatives around the world developing modern “advanced air mobility” aircraft. All these vehicles will need to be type, process, and operationally certified before they take flight. Even if only a handful of these succeed in progressing to the design and manufacturing stages, it is clear that the certificating authorities will be overwhelmed with applicants. One way to ease the pain is by increasing the role of models and simulation in the certification of aircraft, training devices, as well as pilots. In this talk, we will discuss the role of standards in making this process more efficient.

Presentation Title: Novel Design of an Optimized Morphing EDF Duct

Novel Design of an Optimized Morphing EDF Duct

Electric Ducted Fans (EDF) provide several advantages over conventional propellers. In hover they can provide additional thrust for the same power and rotor diameter meaning smaller footprint of the aircraft on the take-off/landing area. In axial flight the shroud reduces the tip losses of the rotor especially in higher flight speeds. Unfortunately, due to the difference in velocity streamlines in both flight regimes, a shroud optimized for hover will have negative effects on the propulsion efficiency in axial flight. This means that a compromise must be made in the design of a propulsion system intended for fixed wing VTOL aircrafts with efficient axial flight capabilities for ex. using separate systems for hover and for axial flight. Here, an optimization methodology is proposed for a novel design of a morphing ducted fan. Firstly, the optimal geometry for hover was obtained by genetic algorithm optimization. After that, GA optimization was used to obtain the optimal geometry for hover with the introduction of constraints as to be able to create a geometry capable of morphing. In the end, the internal structure of the duct which can provide accurate control of the inlet and outlet was defined by utilizing techniques similar to the ones used in morphing wing designs.
