Abstract
According to one embodiment, a windshield attachment device for coupling a windshield to a body includes a fastener portion, a bolt, and an elastomeric load isolator. The fastener portion has an opening therethrough. The bolt is configured to extend through the opening of the fastener portion and couple the fastener portion to the body. The elastomeric load isolator surrounds at least a portion of the fastener portion and separating the fastener portion from the windshield.
Claims18
A rotorcraft, comprising:
- a body;
- a power train coupled to the body and comprising a power source and a drive shaft coupled to the power source;
- a hub;
- a rotor blade coupled to the hub;
- a front windshield comprising a plurality of windshield openings;
- and
- a plurality of attachment devices coupling the front windshield to the body, each attachment device positioned through one of the plurality of windshield openings, each attachment device comprising:
- a fastener portion having an opening therethrough, the fastener portion comprising a head portion and a body portion;
- a bolt extending through the opening of the fastener portion and coupling the fastener portion to the body;
- and
- an elastomeric load isolator surrounding at least a portion of the fastener portion and separating the fastener portion from the front windshield, the elastomeric load isolator comprising a head portion and a body portion, wherein each windshield opening is sufficiently larger than the body portions of the fastener portion and the elastomeric load isolator of each attachment device such that a gap exists between the body portion of the elastomeric load isolator and an interior surface of the windshield opening when each attachment device is positioned through one of the plurality of windshield openings.
