Question

I need help with writing a small paragraph about their flight pattern

Discuss the flight pattern of mosquitos and contrast them to honeybee, mantis, and dragonflies?

Answer 1

Solution: Mosquito- The wing-stroke of the mosquito is significantly smaller than that of other insects The frequency of wing beat is over 700Hz. Sweep of their wing is less than 40 degrees and also the rapid rate of movement helps to lift them from the ground. It uses a trailing edge vortex. The vortex forms atthe edge of the wing, but moves away from the body as it forms. It can stop its downward strokes and reverse its wings, so as to catch more of this trailing vortex 1. 2. Honey bee The honeybees have a rapid wing beat and it flaps its wings 230 times every second. As the insects get smaller, their aerodynamic performance decreases and to compensate, they tend to flap their wings faster. The bees made up for the extra work by stretching out their wing stroke amplitude but did not adjust wingbeat frequency. It uses a leading edge vortex 3. Mantis- shrimp strike is both accelerating and rotational, the factors that alter drag in transient flight may also be relevant to accelerating rotational flight. 4. Dragonfly- Dragonfly wings are smooth surfaces but have distinct corrugations. These corrugations have stressed skin structure composed of girder-like veins and thin cuticle membrane. During flow, flow separates at the ridges, enveloping recirculating eddies that might play a role in reducing skin friction drag or modulating the lift coefficient. Mosly they fly by flapping their wings with a leading-edge vortex on the forewing and attached flow on the hindwing. When flapping in-phase, they exhibited separated flow at the leading edge of the forewing, creating a separation bubble defined by an enclosing streamline that reattached on the hindwing, delineating a very large leading-edge vortex over the wings as they acted as a single aerodynamic surface.
