    Abstract: A gas turbine engine is provided having a turbomachine comprising a compressor section, a combustion section, and a turbine section arranged in serial flow order, the compressor section having a high pressure compressor defining a high pressure compressor exit area (AHPCExit) in square inches and the turbine section having a drive turbine defining a drive turbine exit area (ADTExit) in square inches, the turbomachine further comprising a drive turbine shaft coupled to the drive turbine; wherein the gas turbine engine defines a maximum exhaust gas temperature (EGT) in degrees Celsius, a maximum drive turbine shaft torque (TOUT) in Newton meters, and a corrected specific power (CSP) in Newtons squared times degrees Celsius over meters squared, wherein the corrected specific power is determined as follows:

    Abstract: The engine is adapted to generate thrust or designed to generate torque includes a combustor, the combustor generates an exhaust gas flow to push the rotor blades of a rotor in a rotor housing, the exhaust gas flow rotates the rotor, shaft, and fan which produces a rotating force and produces an air flow. The rotor housing having a first wall, a second wall, and a third wall which guides the exhaust gas flow until the exhaust gas flow reaches a housing gap at the second wall and the exhaust gas flow moves out from the rotor housing, while the first wall having another housing gap for the air flow to go through to cool the rotor and the cooling process adds torque to the engine. The engine includes an optional wind turbine assembly. An air compressor is either driven by an electric motor or driven by other means.

    Abstract: A diffuser pipe has a tubular body defining a pipe center axis extending therethrough. The tubular body includes a first portion extending in a generally radial direction from an inlet of the tubular body, a second portion extending in a generally axial direction and terminating at a pipe outlet, and a bend portion fluidly linking the first portion and the second portion. The tubular body has a length defined between the inlet and the pipe outlet. The tubular body has cross-sectional profiles defined in a plane normal to the pipe center axis. An area of the cross-sectional profile at the pipe outlet is at least 20% greater than an area of the cross-sectional profile at a point upstream from the pipe outlet a distance corresponding to 10% of the length of the tubular body.
