Hi!
This subtitle can be translated as follows:
"The textbook for technical schools of VVS RKKA, volume 1"
There are two abbreviatives:
VVS - Voenno-Vozdushnye Sily - literally means "Military Air Forces"
RKKA - literally means "Worker's ans Peasant's Red Army"
So, if we compose the full no-abbreviative phrase, it can be translated as
"The textbook for technical schools of Military Air Forces of Workers and Peasants Red Army, volume 1"
