Abstract
An apparatus that includes a rotor blade assembly capable of generating vertical lift, one or more propulsion units capable of engaging and disengaging from the rotor blade assembly, an encapsulating housing, and where the encapsulating housing is capable of containing the rotor blade assembly.
Claims46
An apparatus, comprising:
- a first rotor blade assembly capable of generating vertical lift;
- one or more propulsion units capable of engaging and disengaging from the rotor blade assembly;
- and
- an external encapsulating housing mounted on a fuselage, wherein the external encapsulating housing is capable of containing the first rotor blade assembly.
1 more element
An apparatus, comprising:
- an airframe;
- at least one rotor blade assembly;
- and
- means for stowing the at least one rotor blade assembly within an external encapsulating housing attached to a fuselage of the airframe.
1 more element
A method, comprising:
- providing vertical lift to an airframe with a first rotor blade assembly;
- becoming airborne with the vertical lift;
- transitioning to horizontal flight with a thrust from at least one jet engine;
- generating lift by at least one fixed-wing attached to the airframe;
- braking the first rotor blade assembly;
- and
- stowing the first rotor blade assembly within an external encapsulating housing.
