Initial Power

A Jet Fuel Starter (JFS) is used to start the F100 main propulsion engines for the F-15 fighter aircraft. The JFS is a dual rotor machine which consists of a gas generator spool and a power turbine spool. The gas generator turbine wheel was designed to be contained within the turbine case in the event of a JFS overspeed. This is done by the inclusion of a containment ring in the turbine case. The initial power turbine wheel design was not able to be contained by its turbine case. A design decision was made to make this wheel frangible, that is, in an overspeed condition the wheel would break into small pieces which could be contained by the existing turbine case. An alternative design solution is proposed in this paper and an analytical proof-of-concept is presented.

Exit Nozzle

Present study deals with experimental and theoretical performance analysis of an inert gas generator(IGG) which can be used as an effective mean to suppress the fire. The system consists of a gas turbine engine and afterburning system with injection of water, exit nozzle to produce the inert gas. It is generally known that the degree of oxygen content in the product of combustion depends on both inlet and outlet temperature of a combustor. Less the oxygen content in the combustion product higher will be the effectiveness of fire suppression. Injection of water brings additional advantages of suffocating and cooling effects which are both indespensable factors for fire suppressing. The special test rig was manufactured and experimental investigation of IGG system has been carried out. The automatic control system ensured stable operation of gas turbine engine and afterburner, water injection, fuel control and others. During the investigation the main parameters of gas turbine engine and auxiliarly systems were measured: gas temperature and pressure at gas turbine and afterburner exit, fuel flow rate, water mass flow rate, inlet air temperature, water temperature in the cooling chamber, mass flow rate, temperature and velocity of exhaust gas-steam mixture in the exit nozzle, oxygen content in the exit jet. The experimental investigation shows that developed IGG system can work very well for indoor fires but need some modifications in application to outdoor fire suppressing.

Special Process

In handling cargo, some types of ships have different ways. On gas tankers containing LPG, a special process is required in avoiding explosions in cargo tanks and avoiding the waste of cargo into the atmosphere. The process of handling the payload is the inerting porses on the payload tank. This process includes inert gas with oxygen levels of less than 8% to prevent the formation of fire triangles in the payload tank so as to avoid explosions. Inert gas is produced by an engine in the form of an Inert Gas Generator. Inert gas generators have several components, the process of which is interconnected with each other to produce inert gases. Inert gas generators require a good and correct maintenance and repair system considering the purpose of inserting inert gas into the payload tank is significant in terms of safety and security on board. Case study on board MT. Walio gas observes the activities of the inerting process that is disrupted by the waste of inert gas into the atmosphere and has a high dew point value so that inert gas does not enter the tank load. From the results of the case study intended that the components on the gas generator inert do not function properly, some analysis is done by observing the continuity of the process and written data so that it is expected that the case study has the benefit in theory and practice in handling the continuity of the inerting process.

Integral Scheme

The cooling scheme for inert gas exhausting from a small gas turbine engine is presented and its performance, including the gas injector and regenerator, are investigated. A distributed, nonlinear mathematical model used to study the processes in regenerative heat exchangers is also described. An integral scheme of a conjugated problem of a non-stationary heat exchange of both one-dimensional streams and a two-dimensional matrix wall are presented. Comparison of test calculations made using the developed program with experimental data of different authors has shown satisfactory agreement. The extensive study results of quasistationary, dynamic heat and aerodynamic processes in regenerators with four types of matrices are introduced: ceramic matrix with straight rectangular cross-sectioned channels and three types of packings — granite full-spheres, Raschig rings and meshes of stainless steel. For each type of matrix, optimum range of rotation speeds ensures the maximum effectiveness while allowing the minimum aerodynamic resistance to be determined.
