MODULARIZED AIRPLANE STRUCTURES AND METHODS
First Claim
1. A separable motion transmission linkage comprising:
- first linkage portion, substantially elongated, having a first coupling end and a second coupling end, said first coupling end operatively connectable to an actuating device;
second linkage portion, substantially elongated, having a first coupling end and a second coupling end, said first coupling end operatively connectable to a control element;
separable connection means for longitudinally connecting said second coupling end of said first linkage portion to said second coupling end of said second linkage portion, comprising a pair of mutually magnetically attractive members oppositely affixed at said second coupling end of said first linkage portion and said second coupling end of said second linkage portion, enabling said linkage portions to be longitudinally and separably connectable to one another by said attractive magnetic force to form one linkage for motion transmission from said actuating device to said control element;
the strength of said mutual magnetic attraction force sustaining the connection of said first linkage portion to said second linkage portion is sufficient for the linkage connection to withstand the linkage stress under allowed motion transmission operation conditions without disconnection and to disconnect said linkage portions when the linkage parting stress reaches a predetermined level.

Abstract
A modularized airplane includes two separably interconnected modules. A first module, incorporating substantial airplane styles, includes a fuselage portion and at least one wing or stabilizer with an associated control surface. A second module carries a set of essential flight components sufficing airplane operations, including propulsion unit, servo for moving control surface, and power source. Magnetic connectors affixed on the modules facilitate inter-modular structural connection. A control linkage assembly, linking control surface on first module and associated servo on second module, is formed with two portions longitudinally movable and separably connected by two magnetic connectors oppositely affixed on each portion. The structural connection and the servo-to-control surface linkage assembly facilitate substantially effortless inter-modular connections to form a functional airplane, as well as nondestructive inter-modular disconnection. The second module can be connected to different aerodynamic styled first modules to form airplanes for different applications, using same essential components.

6. The separable motion transmission linkage of 1, further comprises means for preventing device coupled to the linkage from being damaged by excessive linkage tension having:
-
first structure, rigid, in fixed positional relationship with said device coupled to the linkage; second structure, rigid, provided at or extending from a predetermined location on the linkage portion said device is coupled to, in physical relationship with said first structure forming a longitudinal movement limit for said linkage portion hence forming a limited operating range for said device; whereby, upon reaching said longitudinal movement limit said first structure is in physical contact with said second structure, preventing said linkage portion from further longitudinal movement, and further longitudinal movement will cause linkage parting stress to reaches said predetermined level, resulting linkage disconnection into said first linkage portion and second linkage portions.
