Abstract
A dual-chamber composite pressure vessel includes a first enclosure formed of a fiber reinforced resin matrix, having a hollow cylindrical central section, and first and second oblate end sections formed integrally over respective ends of the central section to define a first chamber. Also included is a second enclosure formed of a fiber-reinforced resin matrix, integrally with the first enclosure, and having a second hollow cylindrical section which is joined at one end to and extends from the second end section co-cylindrically with the central section of the first enclosure. The second enclosure also includes a third oblate end section formed integrally over the other end of the second cylindrical section to define a second chamber.
Claims10
A fiber-wound composite pressure vessel comprising
- a first chamber-defining enclosure having a first oblate end section, a first cylindrical sidewall formed integrally at one end of the first sidewall with the end section, and a second oblate end section formed integrally with the sidewall at the other end of the first sidewall to enclose and define the first chamber, and
- a second chamber-defining enclosure having a second cylindrical sidewall which is formed integrally with the first sidewall to extend forwardly of the second end section to a termination, and a third oblate end section formed integrally with the second sidewall over the termination thereof to enclose and define the second chamber, and
- wherein the first enclosure, including first and second end section and first sidewall, is comprised of a first layer of wound fiber, wherein the second end section is comprised of additional wound fibers, and wherein the first and second cylindrical sidewalls, and first and third end sections are comprised of a second layer of wound fiber.
A fiber-wound composite pressure vessel comprising
- a first chamber-defining enclosure having a first oblate end section, a first cylindrical sidewall formed integrally at one end of the first sidewall with the end section, and a second oblate end section formed integrally with the sidewall at the other end of the first sidewall to enclose and define the first chamber,
- a second chamber-defining enclosure having a third concave end section which is complementary in shape to the second end section of the first enclosure and is outwardly concave to the second enclosures, a second cylindrical sidewall formed integrally at one end of the second sidewall with the third end section, and a fourth oblate end section formed integrally with the second sidewall at the other end of the second sidewall to enclose and define the second chamber, and
- a layer of fiber-wound composite material laminated to the second end section and to the third end section to join the third end section to the second end section to thereby join the first and second enclosures end to end.
