Project summary

Objectives of the Project are connected with the possibilities of the use of the knowledge and experience of the basic group of researchers-participants of the work for the creation of fundamentally novel system of power supply for industrial and research deepwater submersibles and installations.

The work done covers the investigations fulfilled about four years ago with the assistance of some participants of the Project, the result was the development of a deepwater - down to 6000 meters - prototype of a heat turbine-electric power pack fed by liquid monopropellent missile fuel (the modified hydrazine) has been done.

The work planned to be done foresees the use of the experience obtained and the creation of a new enhanced efficiency commercially competitive system of a perspective deepwater energy source.

The expected result of the work takes into account the novelty of the task, the uniqueness of the prototype built first time in the world and practically the complete absence of literature, describing such systems and processes within. In this situation the enhanced efficiency might be awaited as a figure of about 8 - 9 kg of missile fuel per kWh of electrical power instead of 12,5 - 14 kg/kWh in prototype. Technical approach of the proposed Project realization is based on the investigation of the ways of power system efficiency enhancement with respect to the primary energy source consumption per unit of output electric power and cutting the costs of energy obtaining in the system operation at any depths down to 6000 meters.

The investigations planned incorporate several groups of work, including design-technological solutions. One is the search of optimal solution in choice of the fuel (for example- hydrazinehydrate, kerosene etc.), the other is the creation of effective design of heatgenerator block with the solution of the problem of creation of the fuel-catalyst contact elements, the next is the search of optimal solution of the heatexchange problem between vapor-gas mixture and turbine working body, and, finally, principally search group of investigations of the novel heatexchange methods with respect to the variable values of external hydrostatic pressure up to 600 Bar.

Anticipated results are defined by the problem of perspective realization of heat energy source of high enough efficiency for deepwater submersibles and installations at the average power requirements – up to the order of hundreds of kW. Excluding the atomic energy, which from many points of view nowadays remain noncompetitive, for the indicated power levels and application conditions the heat energy systems practically have no alternatives. Chemical primary and secondary (rechargeable) batteries are noncompetitive from design point of view. Thus, the conclusion about the perspectives of commercial exploitation of heatenergy systems for deepwater submersibles and installations at any depths down to 6000 meters must be the result of the Project.

Role of the foreign participants-collaborators. Taking into consideration the principal novelty of the Project and, in part, available experience of organizations-participants of Project Proposal, judging by the consultations, previously carried out, this role is limited by the support of the Project realization necessity and the will of obtaining of materials containing the results of the Project for the further use but without concrete financial support of the Project today, which might be still available during the period of the fulfillment of the Project.
