The analytic approach of vacuum (Brunel) heating mechanism is generalized to the case of large atomic clusters irradiated by a super-intense femtosecond laser pulse. The hydrodynamic cluster expansion is taken into account in this approach. Simple universal expressions are obtained for the absorbed laser energy by a cluster and for the radius of an expanding cluster. The absorption of laser energy and the cluster expansion are determined by only one dimensionless field parameter.
