  • Publication number: 20190112939
    Abstract: This invention concerns a flow seal (42) for location between opposing components of a fluid flow machine, such as rotor (44) and stator (46) components of a turbomachine (10). The seal (42) has an upstream fin (24) depending from one of components (44) towards an opposing surface (28) of the other (46) of the components and a wall (26) downstream of the fin (24) defining a flow cavity between the fin (24) and wall (26). The fin (24) terminates at a fin tip (24A) so as to define a gap between the fin tip (24A) and the opposing surface (28), through which a leakage flow enters the flow cavity in use. The seal (42) also has a flow guide member (30A) located in the cavity, the flow guide member (30A) being arranged to define a flow path that promotes a vortical flow regime in the cavity. The flow cavity geometry is altered to promote a desired vortical flow regime, such as by way of a projection (39) in an intermediate wall portion of the flow cavity. The vortical flow regime may hinder flow leakage.

  • Publication number: 20190112977
    Abstract: A combined power generation system performing pressure difference power generation includes a pressure difference power generation facility generating electricity by using a pressure change of natural gas; a gas turbine power generation facility including a compressor, a combustor, a turbine, and a generator; and a heating unit to heat the natural gas discharged from the pressure difference power generation facility. A first bypass channel enables the natural gas to bypass the pressure difference power generation facility, and a second bypass channel enables the natural gas to bypass the heating unit. The heated natural gas is heated to a high temperature and then introduced into the combustor of the gas turbine power generation facility. Since the natural gas to be used in the gas turbine power generation facility is preliminarily heated while passing through the preceding power generation facility, the generation efficiency of the gas turbine power generation efficiency is improved.

    Abstract: Various embodiments of the present disclosure provide an aircraft anti-icing system that includes an aircraft engine inlet component, a pressurized air source, and a heat source operable to: (1) heat the leading edge of the aircraft engine inlet component via the heat source to prevent ice formation on the outer surface of the leading edge; and (2) direct pressurized air from the pressurized air source so that it forces water off of the outer surface of the inlet components (and into the external air flow) as the water travels downstream from the leading edge outer surface downstream toward the trailing edge, which prevents runback ice formation.

    Abstract: A fuel supply system for a gas turbine engine has a fuel tank, a main fuel pump for receiving fuel from the fuel tank, and an electric pump also for receiving fuel from the fuel tank. The main fuel pump and the electric pump both deliver fuel to a sharing valve. The sharing valve selectively delivers fuel downstream into a gas generator portion of the gas turbine engine and to an augmentor. A control is programmed to control the sharing valve, such that fuel flows from the main fuel pump to the augmentor, and to the gas generator at higher demand operation, and does not flow from the main fuel pump at lower demand operation. A gas turbine engine and a method are also disclosed.
