I have a setting that is pretty similar to Earth. The tech is at least around WW2 with some steampunk fantasy sprinkled here and there. A global war is about to break out. My civilizations need an agile aircraft that covers the 'fighter' niche.
Unfortunately, they have no access to petroleum on this planet. However, they have access to 2 unique technologies: Anti-gravity tech, and Sun-stones that can act as a battery for high-energy charge storage and powering the Anti-G Tech. They figured they could fuse these 2 technologies to create their aircraft. The Anti-gravity tech provides lift and traditional propellers provide force to move and push the craft; both are powered by electricity from the sun-stone.
Anti-Gravity Context The material that enables the Anti-gravity to move is Gravitite (not a unique name I know). The engineers have figured out ways to fully utilize it. One of the devices is an Altitude Pinner (AP). Once built into the frame of the aircraft, this can provide a few unique manoeuvres:
Vertical Take Off and Landing By adding a charge into the pinner, they can maintain an altitude relative to the dominant gravity well (in this case, the planet's gravity). Increasing or decreasing the charge will change the altitude. Discharging the power to a separate battery can turn off the pin and altitude lock. This can allow vertical take-off and landing without the use of the propeller. The downside is that it only acts against gravity, which is why you still need propellers to move horizontally.
Jump Pinning Once a Pin is activated, if the pinned object is forced to a different altitude, a force attempts to correct the altitude in proportion to the distance from its pinned altitude it has been moved. This can be useful for "slingshot" up or down manoeuvres. Having 2 Pins that can work with different altitudes can allow more advanced manoeuvres.
The Question In real life, we actually did have rear propeller aircraft back in WW1. But due to the extra weight required for the tail, and the invention of the synchronization gear, the tractor plan became favoured instead. The rear propeller design was more of an aesthetic difference then a practical one. My question with all this context about how Anti-gravity tech works. Would a Single Propeller Back Configuration make more sense for this kind of plane then a tractor type?
