Histoire résumée | Schmutzhart?s SCH-1 homebuilt was designed to be small enough to be built in his Washingtion D.C. townhouse. The fuselage was made by bending the outside skin into a wooden jig and riveting the bulkheads and stringers to it from the inside, working through the open top which was then covered. The main wing spar center section was milled from a solid I-beam of 6061 T6 aluminum. The outer spars are of bent flat stock and angled extrusions. Ribs ahead of the spar were bandsawed from dense Styrofoam : aft of the spar they are of sheet aluminum hammered over formblocks. The T-tail was originally all moving, but later modified to have a convetional stabilizer. Approach control is by means of flaps, the setting of which are 0, +4, +45 and +70 degrees. |
