Not as such.
Dynasty is a self-contained game, and TCS is fundamentally a wargame more than an RPG - although you have the means to generate characters as representatives of a dynasty, the Dynasty's Fleet characteristic is a qualitative, not quantitative one - a Dynasty with Fleet 12 has a fleet massively more powerful than its peers in any setting, whilst a Fleet 3 or Fleet 4 can protect its own critical territories but not a lot more.
What an 'average' fleet is, however, depends on the setting and is left to the GM to define. I'd suggest that you set a budget for the 'average' fleet and then pro-rata that budget up or down relative to the Fleet score of each Dynasty.
