The future of aviation technology is transitioning to cleaner, more efficient and higher endurance aircraft solutions. As fully electric propulsion systems still fall short of the operational requirements of modern day aircraft, there is increasing pressure and demand for the aviation industry to explore alternatives to fossil fuel driven propulsion systems. The primary focus of this research is to experimentally evaluate hybrid electric propulsion systems (HEPS) for Unmanned Aerial Vehicles (UAV) which combine multiple power sources to improve performance. HEPS offer several potential benefits over more conventional propulsion systems such as a smaller environmental impact, lower fuel consumption, higher endurance and novel configurations through distributed propulsion. Advanced operating modes are also possible with HEPS, increasing the vehicle’s versatility and redundancy in case of power source failure. The primary objective of the research is to combine all of the components of a small-scale HEPS together in a modular test bench for evaluation. The test bench uses components sized for a small-scale UAV including a 2.34kW two-stroke 35cc engine and a 1.65kW brushless DC motor together with an ESC capable of regenerative braking. Individual components were first tested to characterize performance, and then all components were assembled together in a parallel configuration to observe system-level performance. The parallel HEPS is capable of functioning in the four required operating modes: EM Only, ICE Only, Dash Mode (combined EM and ICE power) as well as Regenerative Mode where the onboard batteries get recharged. Further, the test bench was implemented with a supervisory controller to optimize system performance and run each component in the most efficient region to achieve torque requirements programmed into mission profiles. The logic based controller operates with the ideal operating line (IOL) concept and is implemented with a custom LabView GUI. The system is able to run on electric power or ICE power interchangeably without making any modifications to the transmission as the one-way bearing assembly engages for whichever power source is rotating at the highest speed. The most impressive of these sets of tests is the Dash mode testing where the output torque of the propeller is supplied from both the EM and ICE. Working in tandem, it was proved that the EM was drawing 19.9A of current which corresponds to an estimated 0.57Nm additional torque to the propeller for a degree of hybridization of 49.91%. Finally, the regenerative braking mode was proven to be operational, capable of recharging the battery systems at 13A. All of these operating modes attest to the flexibility and convenience of having a hybrid-electric propulsion system. The results collected from the test bench were validated against the models created in the aircraft simulation framework. This framework was created in MATLAB to simulate the performance of a small UAV and compare the performance by swapping in various propulsion systems. The purpose of the framework is to make direct comparisons of HEPS performance for parallel and series architectures against conventional electric and gasoline configuration UAVs, and explore the trade-offs. Each aircraft variable in the framework was modelled parametrically so that parameter sweeps could be run to observe the impact on the aircraft’s performance. Finally, rather than comparing propulsion systems in steady-state, complex mission profiles were created that simulate real life applications for UAVs. With these experiments, it was possible to observe which propulsion configurations were best suited for each mission type, and provide engineers with information about the trade-offs or advantages of integrating hybrid-electric propulsion into UAV design. In the Pipeline Inspection mission, the exact payload capacities of each aircraft configuration could be observed in the fuel burn versus CL,cruise parameter sweep exercise. It was observed that the parallel HEPS configuration has an average of 3.52kg lower payload capacity for the 35kg aircraft (17.6%), but has a fuel consumption reduction of up to 26.1% compared to the gasoline aircraft configuration. In the LIDAR Data collection mission, the electric configuration could be suitable for collection ranges below 100km but suffers low LIDAR collection times. However, at 100km LIDAR collection range, the series HEPS has an endurance of 16hr and the parallel configuration has an endurance of 19hr. In the Interceptor mission, at 32kg TOW, the parallel HEPS configuration has an endurance/TOW of 1.3[hr/kg] compared to 1.15[hr/kg] for the gasoline aircraft. This result yields a 13% increase in endurance from 36.8hr for gasoline to 41.6hr for the parallel HEPS. Finally, in the Communications Relay mission, the gasoline configuration is recommended for all TOW above 28kg as it has the highest loiter endurance. / Graduate

Le broyage de bois de qualité secondaire est un processus en pleine expansion avec l'augmentation de l'utilisation de la biomasse pour la production d'énergie. La transformation du bois en plaquettes facilite l'automatisation des chaudières. Peu de recherches ont traité le mécanisme de la formation des plaquettes et des efforts de coupe durant cette opération. Lors de ce travail de thèse, nous nous sommes focalisés sur le système de déchiquetage à disque. Un banc d'essais de taille réelle a été construit afin de permettre la variation de plusieurs paramètres, tels que la vitesse de coupe, la vitesse d?amenage, les angles de coupe, la direction d'amenage, la hauteur du contre-couteau, le mode de coupe, le nombre des couteaux et leur saillie.Les expérimentations ont montré que la taille des plaquettes augmente avec l'augmentation de l'avance par dent, l'angle de coupe réel et l'angle de taillant, et diminue avec l'augmentation de la vitesse de coupe. Le processus de la formation des plaquettes est composé de deux mécanismes, qui sont le cisaillement et la propagation de fissures. La mesure des efforts de coupe et de la puissance électrique consommée pour une bande passante pouvant atteindre 3 kHz complète ces données granulométriques. Grâce au banc d'essais de déchiquetage, nous avons pu montrer la corrélation ou l'indépendance de facteurs influents intervenant dans l'optimisation des conditions de coupe / Chipping wood of second quality is a rapidly growing process because of the increasing use of the biomass in energy production field. The utilization of wood chips as a combustible, make it easier to automate the wood boilers function. Few studies were carried out in order to understand the mechanism of the chip formation and the evolution of cutting force during the chipping operation. In this thesis, we focused our analysis on the disc chipper. A test bench of real dimensions was built up in order to be able to vary many parameters such as cutting and feeding speed, cutting angles, feeding direction, anvil height, cutting directions, knives number and their height.Experimental study showed that chip size grows when the feeding tooth, the cutting angle and the sharpness angle increase, whereas it decreases when the cutting speed increases. The process of the chip formation is composed of two mechanisms that are shear and cracks propagation. Measurement of cutting force and electric power consumption for a bandwidth up to 3 kHz bring important results to the chip size study. The chipping test bench allowed us to reveal the correlation or the independency between the parameters needed to optimize the chipping operation

Ce manuscrit traite de la fiabilité de micro-composants électro-mécaniques que l'on appelle des MEMS (Acronyme anglais signifiant Micro-Electro-Mechanical Systems). Les MEMS sont utilisés dans un grand nombre de domaines et le domaine qui nous concerne est celui des télécommunications. Plus précisément, notre domaine de travail se situe autour des radio-fréquences où les MEMS vont principalement réaliser des fonctions de commutation. On appellera ainsi nos composants des MEMS-RF, RF signifiant Radio-Fréquence. Dans ce domaine, les MEMS sont des candidats à fort potentiel grâce à une faible consommation de puissance, leur performance dans le domaine RF, leur encombrement et leur poids. De plus, en utilisant un procédé de fabrication dérivé de celui des semi-conducteurs, leur coût de production reste relativement faible. Dans ce manuscrit, on s'intéresse à la fiabilité de ces composants car c'est le dernier verrou avant une éventuelle industrialisation. Les principaux mécanismes de défaillance sont abordés dans une première partie, puis ce manuscrit se concentre sur l'étude du fluage mécanique et des facteurs d'accélération de modes de défaillance. On verra notamment l'influence de la température et des conditions de fonctionnement sur la durée de vie des commutateurs. / The thesis deals with reliability of tiny electro-mechanical components called MEMS. MEMS stands for Micro-Electro-Mechanical Systems. These components, designed for switching applications, are suitable candidates for telecommunications due to their low power consumption, Radio-Frequencies (RF) performances, compactness and lightness. A MEMS is fabricated using processes of integrated circuit manufacturing that makes its cost relatively low. Few of these components are commercially available and more are expected to be in the market as soon as reliability issues will be solved. Reliability issues studied in the thesis regard mechanical creep and acceleration factors. The mechanical creep occurs in our suspended structures whilst enduring a constant force, it results in deformation of structures and shift of parameters. Two innovative test benches are developed to assess mechanical creep in RF-MEMS switches. The acceleration factors are keys to conduct accelerated testings and predict lifetime of RF-MEMS switches. Parameters such as bias voltage, input-to-output voltage, temperature are varied to assess lifetime of switches and extract these acceleration factors.

L'ensemble des travaux présentés ont été effectués dans le cadre d'une thèse CIFRE entre le laboratoire Quartz EA 7393 et l'entreprise SDI. Ce travail a pour but d'apporter des solutions aux problématiques rencontrées par les ingénieurs de SDI dans le métier des essais. Le cercle de l'étude relève du domaine de la mécatronique. Ainsi, nous nous sommes attachés dans un premier temps à l'étude de l'asservissement des vérins pneumatiques. En effet, lorsqu'il s'agit de commander ce type de vérins sous des perturbations inconnues les algorithmes de commande de SDI ne permettent pas dans ces cas là de satisfaire le cahier des charges. Pour améliorer leurs performances, une commande non linéaire robuste basée sur la théorie de l'homogénéité a été développée au laboratoire Quartz et tester en temps réel à l'aide de Matlab/Simulink et d'une carte dSPACE $1103$. Par la suite, cette commande a été intégrée avec succès sur le logiciel propriétaire X'SPARe. Cette solution a donné toute satisfaction par rapport aux performances et à la fiabilité de la production industrielle.Dans un deuxième temps, un système ABS de type Bosch $5.0$ a été testé en temps réel sur un banc d'essai HIL (Hardware-in-the-loop). Pour cette raison, un modèle du véhicule a été développé sous Matlab/Simulink avec un algorithme de sélection de profils de routes qui a été intégré avec succès dans le logiciel X'SPARe. Les essais effectués en temps réel ont permis de tester l'ABS sous différents profils de routes et de valider le modèle du véhicule sur la base des distances d'arrêt obtenues en se référant aux normes du standard international SAE. / The work presented in this thesis was conducted in the context of a CIFRE contract between Quartz (EA 7393) laboratory and SDI company. This work aimed to provide best solutions to the problems encountered by SDI engineers in craft testing in the field of mechatronics. We focused first on the feedback control synthesis for a pneumatic cylinder. In fact, the control algorithms already implemented within SDI pneumatic systems do not meet the desired specifications. Therefore, a robust non-linear control based on the homogeneity theory was developed at Quartz laboratory and tested in real time using Matlab/Simulink and the dSPACE 1103 card. This control algorithm was successfully integrated within the SDI software X'SPARe. This solution gave entire satisfaction regarding performance and reliability in an industrial context.Concerning the second contribution, a Bosch $5.0$ ABS type system is to be tested in real time on a HIL test bench. For this reason, a vehicle model involving an impulsive observer was developed in Matlab/Simulink including the possibility to specify/estimate the road profiles. This model was also successfully integrated under the software X'SPARe. The tests conducted in real time allowed to characterize the ABS system under various road profiles and to validate the vehicle model as well as the observer based on the stopping distances obtained by referring to the SAE organization standards.
