Abstract | An engineering model of a phased array antenna, cooled using axially grooved heat pipes (AGHP) is presented. Solid state power amplifier's (SSPA) located inside the satellite are wave transmitted to the reflector through waveguides. This integration technique is preferred to minimise electrical losses. However, usually when designing waveguides, minimising antenna losses takes precedence, which leads to an un-optimised design for thermal performance. Because of this situation, a thermal solution has become a challenging problem on this project. With a total heat load of 578 W, it is essential that the waste heat is transferred to the radiator of the satellite which is designed to operate in GEO orbit. This work presents a thermal solution being developed for a satellite phased array antenna that incorporates 4 AGHP's to carry the heat from the SSPA to the radiator. Thermal design work for the antenna and heat pipes completed for the specific boundary conditions for the application, using Icepack® computational fluid dynamics (CFD) thermal software is presented. It is crucial in this pre-development phase to identify problems which can arise from electronic performance loss or thermal issues in advance, both by theoretical design and ground testing. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
