The invention pertains to heat-lifted aerostatic craft, in particular hot-air balloons, and improves the cost-effectiveness and safety of flights. The heat generator comprises a fan (9), a turbine (8) whose vanes are mounted on the fan rim, a combustion chamber (6) with nozzles (1) connected to a fuel gas cylinder, a compressor (7), a pivoting exhaust nozzle (13) and a mixer (14). The turbine (8), compressor (7) and fan are mechanically interconnected. The mixer (14) is situated underneath the lower neck of the balloon skin; from it, a mixture of air supplied by the fan (9) and combustion products is forced up into the balloon skin.
