1. An aircraft for extended flights comprising:
- a nuclear reactor cooled by a gas which includes a helium component;
at leat one turbine which receives expanding heated gas from the reactor;
a propeller driven by the turbine;
heat-radiating tubes located within wings of the aircraft and connected in a closed loop with the turbine for radiating waste heat from the gas to space;
the tubes extending along substantially the entire length of the aircraft wings and directly attached to an inner surface of the upper portions of the wings, covering almost the entire inner surface thereof, to facilitate heat radiation to space without intermediary radiating fins.

Abstract
An unmanned aircraft is equipped with a helium-cooled Brayton cycle nuclear reactor. Heated helium gas drives turbines which in turn rotate propellers to maintain the aircraft aloft for a protracted period of time. After the helium gas expands in the turbines, it is passed through a closed loop including radiator tubes which radiate waste heat from the helium gas to space. The cooled helium gas is returned through the closed loop for repeat of the Brayton cycle.
