cuatro.3. Energetics

In this study, we gratis aansluiting dating measured specifically the aerodynamic power (Paero) added to the air to keep the study subject airborne. However, power is also needed for acceleration and deceleration of the wings (inertial power, Pacc). For this, the flight muscle masss need to be activated, which uses mechanical power (). Ultimately, all power must come from chemically stored energy, and the rate at which this is depleted is termed foundabolic power (Pmet).

We estimated that our study subjects expend approximately 20 mW of aerodynamic power (Paero) when flying (average of the full dataset). Does this make M. sexta an efficient flyer? That question can only be addressed by considering other aspects of the animal’s energy budget. A simplified pathway of the energy flow is presented in figure 5, using estimates from previous studies of hovering M. sexta to compare with our data for flight at 1 ms ?1 . From this it can be seen that the childal flight efficiency (Etot) is approximately 5–6%, assuming previous estimations of Pmet are reliable. The corresponding value for birds and bats has been estimated to be 3–33% and 5.6–15% [19,48], respectively, making hawkmoth flight relatively inefficient in comparison.

Pmech

In vertebrates, Etot is usually equated with the mechanical efficiency of the flight muscle (Emech = /Pmet), as Pacc is most often considered negligible (e.g. ). Fortsätt läsa Electricity can be used for several areas of an enthusiastic animal’s airline
