K550 The 130" span Kinetic will touch 500 mph in dynamic soaring flight winter/spring of 2010/2011, and with this come thoughts of what the next and possibly last speed steps will look like, that being 475-530 and 540-560. The ThunderTaker II is a step in that direction, in that the entire aircraft is optimized for continuous turning flight. What could be done beyond that? The ultimate may return to the 'Kinetic' concept of a winged javelin with a very exotic wing and vestigial fixed stabilizer, possibly none at all. (or possibly with a very tiny fixed vestigial stab and canard) The model would not be molded. Parts would be fabricated directly using vacuum jigs to hold the parts in place during fabrication. This would speed the manufacture process and guarantee fidelity to the intended geometry. The wings max camber would occur at the aerodynamic center chord line, but inboard from that point and outboard from that point the camber would be reduced, but not by the same amount. The wings tipsails would likely be made somewhat larger, specifically if no tail or canard assembly is used. Oddly enough the wing would not have a spar, save only that required to faclitate the joiners and connecting gear. The wings interior would consist of a geodetic lattice of arches attached to the outer skin. Flying surfaces would be manufactured separately from the wings to include a matching reciever bay that is wholly inserted into the wing, resulting in a gapless connection and action. Launch would be normal (hand launch) but it is not out of the question to consider a jetisonable rocket launch. Recovery may likely take the form of a recovery parachute that allows the model to nose in, no different than the X7. It's too far removed from current work to include it as part of the Kinetic line, but the lineage would be present, specifically in the fuselage shape. The concept is not too far fetched. Remember it was not all that long ago folks thought we were nuts to consider 400-450 mph.
