We describe all -gauge-natural operators lifting right-invariant vector fields X on principal G-bundles P → M with m-dimensional bases into vector fields (X) on the rth order principal prolongation of P → M. In other words, we classify all -natural transformations covering the identity of , where is the r-jet prolongation of the Lie algebroid LP=TP/G of P, i.e. we find all -natural transformations which are similar to the Kumpera-Spencer isomorphism . We formulate axioms which characterize the flow operator of the gauge-bundle . We apply the flow operator to prolongations of connections.
