The Orenda OT-4 is a gas turbine which uses a simple regenerative cycle and is being developed as a multipurpose, continuous or emergency unit which will be competitive with the diesel engine and will retain the inherent advantages of the gas turbine. This development program is now in its fourth year. The design and development philosophies used in this engine are discussed briefly. The problems still facing the engine are indicated. Some of the experience and lessons learned from this program are discussed.

The U.S. Navy is developing an intercooled Recuperated (ICR) marine gas turbine, designated the WR-21, for propulsion of future surface ships. The objectives of this development program and the key technical requirements are summarized. The design of the WR-21 is described in considerable, detail. Meeting all of the design requirements for performance, space, weight, reliability, maintainability and life has been challenging. Numerous design tradeoffs and iterations have been performed to optimize the design within the constraints imposed in the ICR technical specification. Integration of the WR-21 engine into the DDG51 Flight IIA ship, which is the U.S. Navy’s first application, has influenced the WR-21 design. This paper discusses the aspects of the DDG-51 application that were factored into the design of the ICR engine in order to reduce installation costs.

The President of Republic of Indonesia issued eight instructions at the CabinetForum on January 4th 2016, one if wich was “Ensuring the Development of the 10 National Tourism Destinations or 10 New Bali, to meet the 2019 tourism target, the increasing of national income from 120 billion into 240 billion.Bali as one of Indonesia’s prime tourism destination has also taken participation in increasing the income. This can be seen from the support given by Bali government to establish the development program of ten rural tourism in the program of the development of Bali in tourism for the next four years to develop the rural tourism. Based on this, the research was aimed at participating in the development of Human Resource in areas where rural tourism take place to allow the villagers to interact intensively with foreign tourists and give their best service.The participation was the design and development of English training with syllabus, lesson plan and training material as its results. The training put much emphasis on the increase of English communication ability based on the potential resource of Bedulu Village as one of rural tourism. The method of the research was Design and Development, porposed by Ellis and Levy (2010), that consists of several phases in designing and developing English training. It is expected that the output of the study will results in the realization of society service at rural tourism as English training.
