A rotary engine is described including: (1) a rotor located within a housing, the rotor configured with a plurality of rotor vane slots; (2) a vane separating an interior space between the rotor and the housing into at least a trailing chamber and a leading chamber, where the vane slidingly engages a rotor vane slot; (3) a first conduit within the rotor configured to communicate a first flow between the trailing chamber and the rotor vane slot; and (4) a lower trailing vane seal affixed to the vane, the lower trailing vane seal configured to valve the first conduit with rotation of the rotor. Optionally, a second conduit within the rotor is configured to communicate a second flow between the trailing chamber and the first conduit. Optionally, movement of the vane valves one or more additional fuel flow paths as a function of rotation of the rotor.

1. A rotary apparatus, comprising: a rotor located within a stator, said rotor and said stator defining an interior space therebetween;a vane slidingly engaged in a rotor vane slot of said rotor, said vane separating said interior space into a rotationally trailing chamber and a rotationally leading chamber;a first passage through said rotor configured to communicate fuel flow between said trailing chamber and said rotor vane slot; anda lower trailing vane seal valve statically affixed to a flat trailing side of said vane, said lower trailing vane seal configured to valve said first passage with rotation of said rotor. 2. The apparatus of claim 1, further comprising: a second passage through said vane, said second passage exiting said vane at said trailing chamber. 3. The apparatus of claim 2, further comprising: an upper trailing vane seal affixed to said rotor, said upper trailing vane seal positioned radially outward from said lower trailing vane seal, said upper trailing vane seal configured to valve said second passage as a function of rotation of said rotor. 4. The apparatus of claim 1, further comprising: an outer vane wing-tip surface of said vane comprising an increasing distance between said outer vane wing-tip surface and an inner wall of said stator with increasing rotational distance from a central point of a vane tip of said vane. 5. The apparatus of claim 1, further comprising: a second passage within said rotor configured to communicate a second fuel flow between said trailing chamber and said first passage, said first passage comprising a first cross-sectional area, said second passage comprising a second cross-sectional area, said first cross-sectional area larger than said second cross-sectional area; anda flow booster configured to use flow through said second passage to enhance flow through said first passage. 6. The apparatus of claim 2, further comprising: a trailing vane wing port of a trailing vane wing of said vane, said trailing vane wing extending radially outward from a tip of said vane into said trailing chamber, said second passage exiting said vane at said trailing vane wing port. 7. The apparatus of claim 6, further comprising: a section of an inner wall of said stator configured to, upon rotation of said vane past said section, force an inner edge of said trailing vane wing into proximate contact with at least one of said first passage and said second passage. 8. The apparatus of claim 1, further comprising: a non-elliptical inner wall of said stator, said non-elliptical inner wall configured to, as function of rotation of said rotor, sequentially:force said lower trailing vane seal of said vane into a first position sealing said first passage; andallow outward radial movement of said lower trailing vane seal of said vane into a second position opening said first passage. 9. A method for using a rotary system, comprising the steps of: rotating a rotor within a stator, said rotor and said stator defining an interior space therebetween;sliding a vane within a rotor vane slot of said rotor, said vane separating said interior space into a rotationally trailing chamber and a rotationally leading chamber;communicating a fuel flow between said trailing chamber and said rotor vane slot through a first conduit through said rotor; andvalving said first conduit with rotation of said rotor using a lower trailing vane seal immovably affixed to said vane, wherein said step of valving further comprises the steps of: opening output of said first conduit by moving both said vane and said lower trailing vane seal immovably affixed to said vane radially outward from a center of said rotor; andclosing output of said first conduit by moving both said vane and said lower trailing vane seal immovably affixed to said vane radially inward toward a center of said rotor. 10. The method of claim 9, further comprising the step of: using said lower trailing vane seal to open said first conduit to said rotor vane slot during a power stroke of said rotary system. 11. The method of claim 9, further comprising the step of: using said lower trailing vane seal to close said first conduit to said rotor vane slot during an exhaust phase of said rotary system. 12. The method of claim 9, further comprising the steps of: providing a passageway through said vane; andgenerating a force by passing a pressurized fuel through said passageway into said trailing chamber, said force aiding rotational movement of said rotor. 13. The method of claim 12, further comprising the step of: passing the pressurized fuel from a shaft of said rotary system to said passageway of said vane. 14. The method of claim 12, further comprising the step of: passing the pressurized fuel from said first conduit to said passageway of said vane. 15. The method of claim 9, further comprising the steps of: providing a second conduit in said rotor from said trailing chamber to said first conduit; andusing a flow booster to enhance flow through said first conduit, said flow booster using fuel flow through said second conduit. 16. The method of claim 9, further comprising the steps of: opening said first conduit through outward radial movement of said lower trailing vane seal of said vane into a first position; andclosing said first conduit through inward radial movement of said lower trailing vane seal of said vane into a second position. 17. A rotary engine apparatus, comprising: a rotor eccentrically located within a housing, said rotor and said housing defining an interior space therebetween, said rotor configured with a plurality of rotor vane slots, wherein said housing comprises an about elliptical inner wall;a set of vanes spanning a distance from said set of rotor vane slots to said housing, said set of vanes separating said interior space into a plurality of chambers, said plurality of chambers comprising at least a trailing chamber and a leading chamber separated by a first vane of said set of vanes, said first vane slidingly engaged within a first rotor vane slot of said set of rotor vane slots;a first conduit within said rotor configured to communicate a first fuel flow between said trailing chamber and said first rotor vane slot; anda lower trailing vane seal affixed to a flat rotationally trailing side of said first vane, said lower trailing vane seal configured to valve said first conduit with movement of said first vane. 18. The apparatus of claim 17, further comprising: a first cutout variation of an inner wall of said primarily elliptical inner wall of said stator within a one o'clock to three o'clock position, said first cutout variation configured to allow extension of said first vane to a first extension distance exceeding a first original vane extension distance to said first primarily elliptical inner wall at about a two o'clock position, wherein a twelve o'clock position comprises a point of rotation of said rotor of first extension of said first vane. 19.
