Tip turbine engine support structure
First Claim
1. A tip turbine engine assembly comprising:
- a first rotationally fixed member disposed about an engine centerline;
a support member extending radially from said first rotationally fixed member;
a second rotationally fixed member attached to said support member and disposed coaxially with said first rotationally fixed member;
a rotor mounted between said first rotationally fixed member and said second rotationally fixed member, said rotor comprising compressor blades that extend radially outward;
a guide vane extending radially outwards from the second rotationally fixed member; and
a housing disposed radially outward of the first rotationally fixed member, wherein the housing is attached to both the first rotationally fixed member and the guide vane.

Abstract
A tip turbine engine assembly according to the present invention includes a load bearing engine support structure (12). The engine support structure (12) includes an engine support plane (P) that is substantially perpendicular to an engine centerline (A) and first rotationally fixed member (50) disposed about the engine centerline (A) and cantilevered from the engine support plane (P). A support member extends radially outward from the first rotationally fixed member (50) and structurally supports a second rotationally fixed member (58) that is coaxial with the first rotationally fixed member. A rotor is mounted on the first rotationally fixed member and rotates about the engine centerline (A).
