  • Optical sliprings
    Patent number: 4027945
    Abstract: Optical slip rings are disclosed which permit signals to be transferred f a rotating body to a non-rotating body without any physical contact. Fiber optic bundles are utilized to conduct light signals on one body to separate fiber optic bundles on the other body.

  • Fan lift-cruise v/stol aircraft
    Patent number: 4022405
    Abstract: An aircraft for making vertical and short field takeoffs is powered by a ass turbofan engine having a core turbojet and a bypass fan. For vertical takeoffs, the efflux from the bypass fan is deflected downward to create lift. Exhaust from the core turbojet is ducted to turbine driven lifting fans at remote locations to create supplemental lifting forces which also provide aircraft control and stability. For cruise, the bypass fan efflux is discharged aft until sufficient forward airspeed is attained that exhaust gas flow to the lifting fans may be shut off, and exhaust gas flow may also be discharged aft.
