A STUDY of possible economic advantages to the aircraft operator of utilizing the internal cooling potentialities of water to assist aircraft-engine cooling and increase detonation limited powers is presented here.Cost analysis is made of three methods of increasing airplane performance by water injection, namely: It is concluded by the author that if the water to be used for cooling does not displace an equivalent weight of payload, a maximum saving of 7% at sea level and 18% at 25,000 ft can be realized in direct operating cost with water. At the same operating cost a performance increase of 3% at sea level and 12% at 25,000 ft can be realized. However, if the water carried results in an equivalent loss in payload, the operating cost may be doubled if water injection is used.
