If a 1MW LENR reactor can be built that weighs <430 lbs ( 192 Kg ) then it could be easily bolted or ducted to the rear combustor can of an RR300 turbine in an MD520 helicopter if it can heat to 1145 °F or 618 °C. The weight of the fuel that wouldn't be needed is most of the weight allowable for the reactor. The volume available is about 100 gallons ( 13 ft^3 or 0.38 m^3; 2.4 feet cube, 72cm/side ) including the fuel volume and the space around the combustor can. Infinite endurance aircraft :-) !
