Journal ArticleDOI

Quick Estimates of Flight Fitness in Hovering Animals, Including Novel Mechanisms for Lift Production

TL;DR: In this article, the average lift coefficient, Reynolds number, the aerodynamic power, the moment of inertia of the wing mass and the dynamic efficiency in animals which perform normal hovering with horizontally beating wings are derived.
Journal ArticleDOI

A Rubber-Like Protein in Insect Cuticle

TL;DR: It is shown that resilin is a structure protein in which the primary chains show little or no tendency to form secondary structures; they are bound together in a uniform three-dimensional network (the tertiary structure) with no potential limits as to size.
Journal ArticleDOI

Energetics of Hovering Flight in Hummingbirds and in Drosophila

TL;DR: It is argued that the tilt of the stroke plane relative to the horizontal is an adaptation to the geometrically unfavourable induced wind and to the relatively large lift/drag ratio seen in many insects.
Journal ArticleDOI

Fat combustion and metabolic rate of flying locusts (Schistocerca gregaria Forskål)

TL;DR: The nature and the amount of fuel used by flying Schistocerca gregaria Forskål have been estimated from direct analyses of the total content of fat and glycogen in control groups and in the corresponding flying groups, i.e. groups which had flown continuously for several hours.
Journal ArticleDOI

Biology and Physics of locust flight II. Flight performance of the desert locust (Schistocerca gregaria)

TL;DR: Sotavalta et al. as mentioned in this paper analyzed the relationship between a number of wing-stroke parameters and the lift and thrust produced by the insect under well defined aerodynamic conditions, and found that the effect of altering the body angle is fundamentally different from that of altering a pitch of an aircraft; the lift is controlled and kept constant by the locust and proved that, in this respect, the flight comes near to free flight.
