Abstract:

In this Note a model of the dynamic motion of a single-engine propeller-driven aircraft has been used to illustrate a longitudinal stability problem caused by the effects of power. In a recent general study on the effects of power the problem was shown to be due to changes in propeller slipstream dynamic head acting on a tailplane carrying a download. The problem is here studied in closer detail using the methods developed in the general study. A notable feature if the destabilising effect is that is increases as c.g. moves forward and so opposes the conventional stabilising effects associated with forward c.g. movement. Author
