El Rincon De Celestecielo: Lesiones en la espalda, brazos.. An additional embodiment of the present invention is shown in FIGS. An additional embodiment of the present invention having multiple blades is shown in FIGS. Continuous rotation of the shaft causes the blades to turn within the fluid; in doing so, the blades generate thrust along the shaft longitudinal axis, with the direction of the thrust (and the direction of travel of the vehicle) being determined by which edge of the blades leads during rotation. For example, a vehicle may include a conventional propeller as the primary source of thrust for steady state cruising, and may further include one or more impeller systems 100 attached to the hall for imparting rapid thrust bursts for accelerating, decelerating, or changing direction. The axis that is generally parallel with the direction of travel is the “trust” axis, along which the blade B will surge “fore-and-aft.” The axis that is normal to the plane of blade B is the “heave” axis, along which the blade B will “heave.” The axis that is perpendicular to the thrust and heave axes is the “pitch” axis; the blade B will rotate, or “pitch,” about this axis.

FIG. 23 is a side view of an airship of the present invention which is configured such that the heave axis is tilted downwardly and rearwardly from the hull relative to the intended flight path. The driveshafts 310 are attached to individual servomotors 312 located within the body 302. In operation, because of the thrust axis compliance of the driveshafts 310, the fins 304, 306 extend into an endward position for acceleration (FIG. FIG. 21 is a perspective view of a submarine of the present invention. FIG. 10 is a top view of the watercraft of FIG.

Such propellers are very commonly used as the primary propulsive device in airplanes, power boats and submarines. 23, which shows an aircraft designated broadly at 600. The aircraft 600 includes a hull 602 and a pair of wings 604. The wings 604 are oriented relative to the hull 602 so that the heave axis H is tilted upwardly and rearwardly from the center of the hull 602. This tilting causes the thrust axis T to extend slightly downwardly and rearwardly from the center of the hull 602. Doing so balances both vehicle weight and thrust so that the flight path P is horizontal. Dolor en las articulaciones de las muñecas . In operation, the nose 404 rotates 180 degrees relative to the hull 402. This motion causes the wings 408 to flap relative to the wings 406. However, because of the reaction forces on the wings 406, 408, the nose 404 rotates only 90 degrees relative to the fluid medium, and the hull 402 also rotates 90 degrees relative to the fluid medium in the opposite rotative direction.

As such, the driveshaft 104 should be formed of a material that allows torsional deformation along the pitch axis, and bending such that the blade 106 can deflect relative to the motor 102 along the heave and thrust axes. The blade 106 may be rigid or flexible, and its modulus of elasticity can be constant through time and/or the blade volume (as when formed of a single material), or its modulus of elasticity can be arranged to accommodate the differing distributed loads acting on the blade, redirecting fluid flow in the desired manner, or its modulus of elasticity may be variable, such as through the inclusion of a strain-rate dependent viscoelastic material or an electromagneto-rheological fluid. Each blade is mounted such that its longitudinal axis is generally normal to the shaft and its transverse axis forms an oblique angle with the shaft.

Also, the direction of thrust production is unchangeable, always coaxial with the propeller shaft, and requires extra machinery for redirecting that shaft or the thrust using a rudder. The boat 150 includes a trolling motor assembly 152 having a motor 153 with a downwardly-extending driveshaft 154 attached to a blade 156. Preferably, the motor 153 is mounted to the hull 151 with a compliant, tuned bracket 151 a. In operation, the driveshaft 154 pivots about its longitudinal axis through a desired angle, which in turn pivots the blade 156. The compliance in the driveshaft 154 and mounting bracket 151 a provide the trolling motor assembly 152 with the ability to drive and maneuver the boat 150 easily in any direction without imparting unwanted vibration or shaking during cruising or maneuvering. These motions cause each wing 406 to first flap to clap one of the wings 408, then flap oppositely to clap the other wing 408 (see FIG.

FIG. 17 is a front view of the watercraft of FIG. Alternately adjacent fish of approximately the same size undulating 180 degrees out of phase exhibit up to five times greater range or speed for the energy input as a fish swimming alone. The first is a proximity jet enhancement that has been observed (and confirmed mathematically) for fish swimming side-by-side. In this configuration, the fins 354 can benefit from two different effects observed in fish swimming as a school. The driveshaft 154 is preferably elastic and compliant in thrust, heave and pitch.

BLOG FISIOTERAPIA ANHANGUERA SOROCABA: Aulas de Hidroterapia The submarine 550 includes an underwater hull 552 having a blunt nose, a tapered tail, and a plurality of undulating fins 554, each of which is formed of a cast rubber sheet. The wave propagation produces thrust that propels the submarine in the desired direction. In the submarine 350, the fins 354 can be controlled by individual motors, or can be controlled by other rotary input means. Those skilled in this art will also appreciate that the concept of many fins can be extended to other types of water craft, such as a boat, which can have rows of fins mounted to its underside or can have a single row of fins mounted to the underside of its stem. Dolor en la parte de arriba de la pierna derecha . This nodeless motion is similar to that of the motions followed by the propelling limbs, wings, bodies, or tails of many animal species as they swim or fly.

The torsional and pitch compliance the wings 406, 408 ensure rearward jet flow on both the “clap” and the “fling” motions. It is another object of the present invention to provide a fluid impeller that can produce smooth cruising thrust. Another embodiment of the present invention is illustrated in FIG. FIG. 18 is a perspective view of the watercraft of FIG. While not wishing to be bound by any one theory of operation, it is believed that the employment of a tuned compliant shaft 104 enables the blade 106 to smoothly impart components of its motion to an attached vehicle that ordinarily (i.e., in impeller systems in which a non-compliant, or non-tuned transmission means is employed) are transmitted to the vehicle as shaking or vibration. Such a vehicle may have a plurality of bladelike elements and a plurality of tuned compliant transmission shafts, each of which is attached to a respective one of the plurality of bladelike elements.

If the blade 106 of the impeller system 100 is formed of a shape memory polymer, then one may change the stiffness of the blade 106 to improve its use for either purpose. Sweeping or flapping blades employ a rigid driveshaft that is rotatively mounted in a bushing on the hull of the vehicle. 6 showing the opposed reciprocating motion of the blades. FIGS. 19 and 20 shows an embodiment of the present invention in which a circular ring is employed as an impeller. The foregoing embodiments are illustrative of the present invention, and are not to be construed as limiting thereof Although exemplary embodiments of this invention have been described, those skilled in the art will readily appreciate that many modifications are possible in the exemplary embodiments without materially departing from the novel teachings and advantages of this invention.
