Piezoelectric thermo electromechanical energy harvester for reconnaissance satellite structure

Mughal, M. (2019). Investigation of tensile and inplane shear properties of carbon fiber reinforced composites with and without piezoelectric patches for microcrack propagation using extended finite element method. AbstractThe smart materials are capable to integrate the remarkabale active functions into a traditional structure of the composites. There is a wide reaseach possibility towards the embedded patches into a composite primary structure. This particular study aims to investigate the effect of the embedded smart materials in a conventional composite laminate. Carbon Fiber Reinforced Composite specimens with and without PZT piezo elements embedded in the structure are studied for Tensile, In-plane Shear and three point bending properties. Previously researched mechanical behaviour and the operational influence of the piezo sensors are sequentially analysed, particularly for the elecetric capacitance during all the categories of testing. The limitations have also been studied into the comparison of the structure with and without the piezoelectric material patches. The extended Finite Element (XFEM) modelling approach has been applied to study the sensorized damage model for the numerical and experimental study. This study also presents simplified and understandable techniques and offers a new direction for the experimental and computational modelling design for the progressive damage, based on the principles of Extended Finite Element Method (XFEM). The extensive experimentation and numerical modelling for interlaminar and intralaminar crack of Carbon Fiber Reinforced Composite CFRCs materials are studied, with and without piezoelectric patches. The experiments and simulations are designed and grouped into categories of load, boundary conditions and types arranged accordingly for fracture, delamination, fiber breakage and matrix crack towards the damage evolution. The dimensions of the specimens and the effects are also studied regarding lengths, thickness and width in multiple categories. The loading cases of tension and the inplane shear are studied for multiple cases for numerical as well as experimental investigation having different orientations and dimensions. The delaminated and fractured mode I and mode II specimen were analysed for the expected and the real time values of strength to figure out the precise values of trends to predict the composite properties.

“…These modules are pre-tested, therefore the integration can be done much faster. These panels are quickly assembled in standard CubeSat structure as well as custom configurations [18][32] [33]. The PCB of one such panel contains four layers of printed magnetorquers in addition to all necessary electronics as shown in Fig.…”

Attitude Control System (ACS) is one of the critical subsystems of any spacecraft andtypically is in charge of de-tumbling, controlling and orienting the satellite after initial deployment and during the satellite operations. The magnetorquer is a core magnetic attitude control actuator and, therefore, a good choice for nanosatellite attitude stabilization. There are various methods to achieve control torque using the magnetorquer. An innovative design of printed magnetorquer has been proposed for the nanosatellites which is modular, scalable, cost effective, less prone to failure, with reduced harness and power consumption since the traces are printed either on top layer or inner layers of the printed circuit board. The analysis in terms of generated torque with a range of input applied voltages, trace widths, outer and inner-most trace lengths is presented to achieve the optimized design.The optimum operating voltage is selected to generate the desired torque while optimizing the torque to the power ratio. The results of analysis in terms of selection of optimized parameters including torque to power ratio, generated magnetic dipole moment and power consumption have been validated practically on a cubesat panel. The printed magnetorquer configuration is modular which is useful to achieve mission level stabilization requirements. For spin stabilized satellites, the rotation time analysis has been performed using the printed magnetorquer.

“…Many researchers have analysed there thermal properties and thermal response to voltage generation [6][7][8]. The disadvantage of using such materials is that they can harvest energy for micro or nanoelectronics [9][10][11]. Swati et al [12,13] presented analytical, experimental and numerical model for these materials.…”

As a consequence of energy crisis and pollution around the globe, many countries are shifting towards the renewable energy resources which are environmental friendly too i. e., solar energy. The aim of this research work is to design a solar powered geyser that can be used for domestic as well as for industrial purposes. The analytical model is constructed to understand the behavior of water temperature with respect to time and to the energy that can be generated from solar panel with and without glass glazing. The extensive experimentation was carried out at self designed test rig in Islamabad, Pakistan for six months i. e., August 2017-January 2018. The response of the power output to the time in specific month and its efficiency is predicted and optimized. Moreover, electrical backup was integrated in closed loop feedback circuit to achieve maximum efficiency even in dark cloudy weather or a sunny day. Moreover, it is calculated that how much external power is required by the system in order to perform the task at different time intervals of the day. Analytical results were in good agreement with experimental results, with error of 9%.
