Bird
Flight Muscular System

The supracoracoideus works using a
pulley like system to lift the wing
while the pectorals provide the powerful downstroke.
Most birds have approximately 175 different muscles, mainly controlling
the wings, skin, and legs. The largest muscles in the bird are the
pectorals, or the breast muscles, which control the wings and make up
about 15 - 25% of a flighted bird’s body weight. They provide the
powerful wing stroke essential for flight. The muscle ventral
(underneath) to the pectorals is the supracoracoideus. It raises the
wing between wingbeats. The supracoracoideus and the pectorals together
make up about 25 – 35% of the bird's full body weight.
The skin muscles help a bird in its flight by adjusting the feathers,
which are attached to the skin muscle and help the bird in its flight
maneuvers.
There are only a few muscles in the trunk and the tail, but they are
very strong and are essential for the bird. The pygostyle controls all
the movement in the tail and controls the feathers in the tail. This
gives the tail a larger surface area which helps keep the bird in the
air.

Abstract -- An ornithopter
having segmented, flapping wings and capable
of bird-like flight. A main driv system provides flapping motion to
the wings. Servo systems are provided for independently moving each
wing forward and backward along a major axis of the aircraft fuselage,
thereby providing a balance subsystem. A single servomechanism controls
upward and downward direction of the wings thereby providing a center
angle control subsystem. Two additional servo systems are provided to
control a tail assembly that provides steering and other ancillary
control functions. Each subsystem is controlled by a dedicated, onboard
microcontroller. One embodiment of the aircraft is remotely controlled
by a wireless data communication link. The aircraft may be constructed
to resemble a natural bird, in both static appearance and flight
characteristics. The aircraft may be scaled from model size to a
full-size, passenger carrying aircraft.

Abstract -- The present
invention provides a wing-flapping flying
apparatus, which can fly by moving its wings similar to a bird hovering
or flying in the air by flapping its wings. The wing-flapping flying
apparatus comprises: a body; a rotating shaft rotatably joined to the
body; driving means for rotating the rotating shaft; and wings
reciprocated between two points and connected to the rotating shaft so
as to be rotated together with the rotating shaft and to be relatively
torsionally rotated with respect to the rotating shaft. The
wing-flapping flying apparatus generates lift throughout an entire
wing-flapping movement without generating lift only throughout the half
of a wing-flapping movement or offsetting the generated lift by the
other half of the wing-flapping movement. Therefore, the wing-flapping
flying apparatus can provide not only a stable flight but also a softly
hovering or ascending and descending flight.

Ornithopter
WO 2009074349
Abstract -- The invention relates to a muscle-powered
ornithopter comprising a
fuselage, a pair of flapping wings which have a modifiable profile or
an aileron in an external wing section located at a distance from the
fuselage, said modifiable profile or aileron allowing the lift to be
modified in a predefined current, and an elevator unit in which the
deflection of the elevator can be modified. The pair of flapping wings
and the fuselage are made of an elastic material, the elasticity of
which allows the pair of flapping wings to be flapped. The flapping
wings are curved downward in a resting position. The elasticity is
calculated such that the flapping wings are urged into a neutral
position during a flight because of the pilot's weight.; The fuselage
is designed to accommodate the pilot in a vertical position relative to
a longitudinal axis of the fuselage such that the pilot can apply
stress to and relieve stress from the aircraft in phases by stretching
and bending his or her legs. The ornithopter further comprises
mechanisms which allow the modifiable external wing sections and the
modifiable deflection of the elevator to be actuated in phase with the
movement of the flapping wings.

Inventor(s): BADYROV
OLEG KAPANOVICH [KZ]
Abstract -- The invention
relates to flying vehicles designed according to a helicopter layout,
in particular to man-powered flying vehicles in which lifting force is
produced by the rotation of a lifting rotor provided with aerodynamic
wings. The inventive helicopter, in particular a man-powered aircraft
comprises a lifting rotor, the rotation of which is carried out in the
more economical manner in comparison with the known prior art due to
the pulsed application of torque to the rotor wings. The technical
result is achieved by the use of the ornithopter principle for rotating
the rotor wings, when energy is periodically transmitted by pulses from
the engine of the craft (from the pilot, i.e., from his legs) to a
drive for carrying out flapping motions by the wings and a horizontal
"pulling" component of the lifting force, produced on the flapping
wings, generates torque on the aircraft rotor.

Abstract -- A winged device
comprises an axial support mounted for reciprocating rotary motion
about a longitudinal axis of the support, a first wing vane 1 mounted
to the axial support 3 for rotation therewith, and a second wing vane 2
hingedly mounted to the axial support 3. The first wing vane 1 is
