Abstract: Nosecone and tailfin designs for aerodynamic systems are disclosed. The designs increase the usable volume within the fuselage of the aerodynamic system while still maintaining the same length for the aerodynamic system. In an example, the nosecone is truncated and includes a blunted tip compared to standard nosecone designs, which allows for more useable space along the length of the aerodynamic system. A tailfin structure is fabricated as a separate piece (separate from the fuselage of the aerodynamic system) and slips over a portion of one end of the fuselage, thus allowing useable volume within the fuselage beneath the tailfin structure. The tailfin structure also includes a hollow cavity for holding componentry (e.g., an RF transmitter, receiver, or transceiver device) with wires that feed through the tailfin structure and into the fuselage of the aerodynamic system.

Abstract: A control system for electronically linked pilot and co-pilot inceptors (103) permits an asymmetric roll axis feel depending on whether an inceptor is moved inboard or outboard. A circuit (401) receives a signal representative of a force applied to the pilot's inceptor resulting from a side-to-side movement and detects if the force applied is in an inward or an outward direction. A gain factor is applied to the received force signal to produce a factored force signal. The gain applied to a signal representative of force applied in an outward direction is greater than the gain factor applied to a signal representative of force applied in an inward direction. A summer (212, 213) sums the factored force signal with a corresponding factored force signal derived from force signals from the co-pilot's inceptor to produce a modified force signal for use in a force feedback control system associated with each inceptor.
