  • Multimodal Hybrid Powerplant for Unmanned Aerial Systems ( UAS ) Robotics
    Twenty-Fourth Bristol International Unmanned Air Vehicle Systems Conference, 2009
    Co-Authors: Richard R. Glassock, Jane Y. Hung, Luis Felipe Gonzalez, Rodney A. Walker
    Abstract:

    Most UAS propulsion systems currently utilize either Internal Combustion Engines (ICE) or Electric Motor (EM) prime movers. ICE are favoured for aircraft use due to the superior energy density of fuel compared to batteries required for EM, however EM have several significant advantages. A major advantage of EM is that they are inherently self starting have predictable response characteristics and well developed electronic control systems. EMs are thus very easy to adapt to automatic control, whereas ICE have more complex control response and an auxiliary starting motor is required for automated starting. This paper presents a technique for determining the performance, feasibility and effectiveness of Powerplant hybridisation for small UAS. A Hybrid Powerplant offers the possibility of a radical improvement in the autonomy of the aircraft for various tasks without sacrificing payload range or endurance capability. In this work a prototype Aircraft Hybrid Powerplant (AHP) was designed, constructed and tested. It is shown that an additional 35% continuous thrust power can be supplied from the hybrid system with an overall weight penalty of 5%, for a given UAS. Dynamometer and windtunnel results were obtained to validate theoretical propulsion load curves. Using measured Powerplant data and an assumed baseline airframe performance characteristic, theoretical endurance comparisons between hybrid and non-hybrid Powerplants were determined. A flight dynamic model for the AHP was developed and validated for the purposes of operational scenario analysis. Through this simulation it is shown that climb rates can be improved by 56% and endurance increased by 13%. The advantages of implementing a hybrid Powerplant have been baselined in terms of payload range and endurance. Having satisfied these parameters, a whole new set of operational possibilities arises which cannot be performed by non-self-starting ICE only powered aircraft. A variety of autonomous robotic aircraft tasks enabled by the hybrid Powerplant is discussed.

  • Design, modelling and measurement of a hybrid Powerplant for unmanned aerial systems
    Australian Journal of Mechanical Engineering, 2008
    Co-Authors: Richard R. Glassock, Jane Y. Hung, Luis Felipe Gonzalez, Rodney A. Walker
    Abstract:

    Hybrid Powerplants combining internal combustion engines and electric motor prime movers have been extensively developed for land- and marine-based transport systems. The use of such Powerplants in airborne applications has been historically impractical due to energy and power density constraints. Improvements in battery and electric motor technology make aircraft hybrid Powerplants feasible. This paper presents a technique for determining the feasibility and mechanical effectiveness of Powerplant hybridisation. In this work, a prototype aircraft hybrid Powerplant was designed, constructed and tested. It is shown that an additional 35% power can be supplied from the hybrid system with an overall weight penalty of 5%, for a given unmanned aerial system. A flight dynamic model was developed using the AeroSim Blockset in MATLAB Simulink. The results have shown that climb rates can be improved by 56% and endurance increased by 13% when using the hybrid Powerplant concept.

  • simulation of operating conditions of a home energy system composed by home appliances and integrated pv Powerplant with storage
    Energy Procedia, 2016
    Co-Authors: F Zuccari, A Santiangeli, Fabio Orecchini
    Abstract:

    Abstract Electricity produced exploiting renewable energy sources has been continuously growing during the last years. It is mainly generated by converting solar radiation and wind, both characterised by well-known aleatory uncertainties. In Italy in 2014 (source GSE) photovoltaic (PV) installed power was 18.6 GW with an energy production of 22.3 TWh, while wind turbines installed power was 8.7 GW with an energy production of 15.2 TWh, both covering an important share of the Italian energy demand. A significant number of Powerplants with aleatory uncertainty of electricity production has an important impact on the distribution grid management, where more and more resources have to be allocated to guarantee the due reserve margin to the dispatching market [1] . So, it becomes necessary to reduce the aleatory uncertainty of produced energy to mitigate the negative effects without limiting the market penetration of “zero emission” renewable sources. Large wind and PV power production plants can take advantage of forecasting models and storage systems. In the case of home integrated PV energy production plants, the impact mitigation on the grid can also be achieved through an appropriate design of the whole onsite energy system composed by both electricity using appliances, and PV Powerplant (with storage). The objective of this new integrated design is the limitation of electricity exchange with the grid. That need has been partially taken into consideration by the Italian legislation on SEU (User's efficient system) introduced by the Law 115/08: SEU's self-consumption of electricity is not charged with transmission, distribution, dispatching and general costs.
