ABSTRACT:
An arrow adapted to be mounted on an archery bow comprises a unitary elastomeric diaphragm having: a clamped periphery, a central opening for receiving an arrow shaft and plural openings through which vanes of the arrow are projected as the arrow is released from the box. The slots intersect and radiate from the opening. The diaphragm is arranged so (a) the arrow shaft is substantially surrounded by and is in contact with interior surfaces of the diaphragm when the arrow is nocked and (b) the interior contacting surfaces as well as diaphragm portions surrounding them move in the direction of arrow flight as the arrow is released. A metal stiffening ring for the clamped diaphragm periphery prevents movement of a peripheral unclamped portion of the diaphragm between the clamped periphery and the portions of the diaphragm which move as the arrow is released.
