Abstract: A bypass housing receives a fan and defines a front end. An airflow path delivers air into an inlet duct over a limited circumferential extent of the bypass housing. An airflow path passes across a low pressure compressor rotor. An airflow path passes through a core engine, which includes a high pressure compressor rotor, a combustor, and a high pressure turbine rotor. Products of combustion downstream of the high pressure turbine rotor pass into an intermediate duct and then across a low pressure turbine rotor. The low pressure turbine rotor is positioned closer to the front end of the engine than is the high pressure turbine rotor. The low pressure turbine rotor is positioned axially intermediate the low pressure compressor rotor and the fan. The low pressure turbine rotor drives both the fan and the low pressure turbine rotor. An aircraft is also disclosed.

Abstract: A gas turbine engine may include an axial high pressure compressor having an air flow pathway positioned between the inner and outer rim of the rotor section.

The pathway may be a tube having an ovoid cross sectional shape and is substantially co-planar to the outer surface of the outer rim. The pathway may traverse the rotor section from the first rotor segment to the rear hub.

Abstract: A plurality of virtual instant tickets are loaded onto a memory of a microprocessor that is physically provided to the consumer. The consumer is physically given a small object, such as a bank card or hotel room key card that has the microprocessor embedded therein. The memory of the microprocessor includes a validation number of each virtual instant ticket, and the winning or losing outcome of each virtual instant ticket and the value of any winning outcome. A purchase is made to unlock a portion of the virtual instant tickets, thereby allowing that portion of tickets to be played. The consumer uses a computing device that interacts with the microprocessor to play the tickets and informs the consumer of the outcome. Additional virtual instant tickets may be unlocked with subsequent purchases. The memory of the microprocessor is updated to indicate the one or more virtual instant tickets that were successfully played.
