Abstract Research is at present being carried out at the Turin Polytechnic University with the aim of designing an HAVE/UAV (high altitude very-long endurance/unmanned air vehicle). The vehicle should climb to 17-20km by mainly taking advantage of direct Sun radiation and thereafter maintain a level flight; during the night, a fuel cells energy storage system would be used. A computer program has been developed to carry out a parametric study for the platform design. The solar radiation change over one year, the altitude, masses and efficiencies of the solar and fuel cells, and the aerodynamic performances have all been taken into account. The parametric studies have shown how fuel cells and solar cells efficiency and mass have the most influence on the platform dimensions. A wide use of high modulus CFRP has been made in designing the structure in order to minimise the airframe weight. A first configuration of HELIPLAT® (HELIos PLATform) was worked out, following a preliminary parametric study. The platform is a monoplane with eight brushless electric motors, a twin-boom tail type with an oversized horizontal stabiliser and two rudders. The co-ordinates at the root and along the wing span as well as the wing planform were optimised to achieve the best efficiency. Several profiles and wing plans have been analysed using the CFD software Xfoil and Vsaero. Several wind-tunnel tests were carried out to compare the analytically predicted performances. A preliminary design of a scale-sized technological demonstrator was completed with the aim of manufacturing a proof-of-concept structure. A FEM analysis was carried by using the Msc/Patran/Nastran code to predict the static and dynamic behaviour of the UAV structure.

Solar energy is a natural resource and can be harnessed to provide clean electricity to hydrogen production system. However, control problems still remain due to the large variety of PV output power with different solar radiation levels. To better investigate about this problem, a model that the PV power plants are integrated with production and storage system such as hydrogen generator, electrolyzer, PV system and hydrogen tank is needed. The focus of the present paper is to develop an integrated simulation model that can be effective and user friendly to predict the dynamic behaviors of a solar powered hydrogen system. The solar irradiance and temperature are the independent variables that act as the input variables to the model. The analyzed results could be used for analyzing the system performance, and also for sizing and designing the system. The integrated model is created by using Matlab Simulink simulation platform which allows the users to define the system specification. The particular information of the system such as power generated by the solar system, volumetric production & etc. can be clearly shown and determined in the simulation platform.

The rural-isolated agricultural region in Iraq and some developing countries lack access to electricity, and thus the primarily alternative is to use diesel water pumping systems to irrigate their crops. However, due to a rise in the oil's price on the international market, toxic pollution from burning oil, high maintenance costs, and short lifespans have been challenged to create more viable alternatives. Renewable energy can limit the use of fossil fuels, particularly by using the solar-powered water pumping system. This article aimed at finding an optimal design for a direct-coupled photovoltaic water pumping system in Iraq. The article presents the significant design aspect for an optimal system, such as the groundwater aquifer depth, installation aspect, cost, and irrigation efficiency. The design offers a combination of sprinkler and environmentally sustainable and cost-effective photovoltaic technology to reduce electricity and water use. A deep well to the storage system is adopted with, 40m maximum well depth, 90m3 reservoir, 1200W submersible pump, and 1800 Wp, which can supply water to 12 greenhouses for three days. The yearly results show pumping efficiency is increased up to 42.6%, used water need is achieved at 10950 m3, and unused energy is reduced by 48.8%.

Absorption Refrigeration System

India suffers from the wastage of a large amount of agricultural produce due to the lack of proper post-harvest storage system. In this paper, an attempt has been made to propose a novel hybrid solar thermal and biomass driven refrigeration system. The refrigeration cycle used here employs a LiBr-H­­­­2O vapour absorption refrigeration system used for storage of potatoes in cold storage. The objective of the hybrid power system proposed here is to produce a favourable micro-climate inside the cold storage throughout a calendar year irrespective of the seasonal variations in weather. The modelling equations of the proposed system have been developed and solved with the help of Engineering Equation Solver for the location of New Delhi (28o35’ N, 77o12’ E). The results of the proposed model are validated against a reference model study available in literature and a very good agreement is achieved with a root mean square error of 0.98% in the value of COP. A rudimentary cost analysis has also been included to assess the economic viability of the proposed system. The study thus reinforces the viability of using a solar biomass hybrid system for operation in the rural areas of a developing nation like India.
