摘要

Ahybrid airship denotes one kind of aircraft that combines the use of aerodynamic and buoyant lift. It is supposednto achieve the best combination of the high-speed characteristics of the airplane and the heavy-lifting capacity of thenairship. In this work, an improved flight performance analysis method for a hybrid airship is proposed, aiming tonprovide a set of new formulas that aremore suitable for a hybrid airship. The new formulas for analyzing the steadynand accelerated performances of a hybrid airship are derived in a systematic way. The main advantage of the newnformulas is that the relationship between the flight performances of a hybrid airship and airplane is indicated in anclearer and simpler expression. Base on the derivation, the theoretical comparisons are performed to show thenadvantage and disadvantage of the hybrid airship. An example of estimating flight performance of a model hybridnairship is presented to preliminarily demonstrate and evaluate the developed method, which shows a reasonablenresult.
