They are playing around in local optima.

Lift-Span Tech creates a new CFD Apex (patent pending)
which is the first step to optimal designs of all subsonic aircraft.

Detailed postings anticipated 10/20/23.


Battery Weight Issues?
Demonstrated solutions to battery weight issues for aircraft include:  1) storing potential energy in altitude during the day and 2) flying during daylight.  SP-Drone will operate at L:D that are 2X to 6X more efficient than contemporary 24/7 aircraft; this translates to major increases in payload capacity; and that payload can be additional power stored in batteries, hydrogen, or ammonia. SP-Drones ultra-high flight efficiency goes a long ways toward overcoming issues with battery/fuel weight.
The most challenging solutions include flights absent daylight and overnight flights.  Many overnight flights (less than 12 hours of night) against at higher speeds and against Earth's rotation can be solved with the just-described battery, hydrogen, ammonia, and/or ambilical power. As a final resort, SP-drone aircraft are based on inexpensive construction methods (sheet stock glued together); and so, it is acceptable for the aircraft to spend less time operating between the hours of 12:00 and 5:00 AM.  Also, a little contemporary fuel can go a long ways as stop gap for night flight.  The bottom line is that proven methods provide market entry positions from which operational logistics and technical solutions will evolve.
