  • A seismic source generates controlled seismic energy that is used in both reflection and refraction seismic surveys. A seismic source can be simple, such as dynamite, or it can use more sophisticated technology, such as a specialized air gun.
  • a gun that propels a projectile by compressed air
  • An air gun (e.g. air rifle or air pistol) is a rifle, pistol, or shotgun which fires projectiles by means of compressed air or other gas, in contrast to a firearm which burns a propellant. Most air guns use metallic projectiles as ammunition.
  • the local environment; "he hasn't been seen around these parts in years"
  • (part) separate: go one's own way; move apart; "The friends separated after the party"
  • Cause to divide or move apart, leaving a central space
  • (part) something determined in relation to something that includes it; "he wanted to feel a part of something bigger than himself"; "I read a portion of the manuscript"; "the smaller component is hard to reach"; "the animal constituent of plankton"

BOEING B-52D STRATOFORTRESS After it became operational in 1955, the B-52 remained the main long-range heavy bomber of the U.S. Air Force during the Cold War, and it continues to be an important part of the USAF bomber force today. Nearly 750 were built before production ended in Oct. 26, 1962; 170 of these were B-52Ds. The B-52 has set numerous records in its many years of service. On Jan. 18, 1957, three B-52Bs completed the first non-stop round-the-world flight by jet aircraft, lasting 45 hours and 19 minutes and requiring only three aerial refuelings. It was also a B-52 that made the first airborne hydrogen bomb drop over Bikini Atoll on May 21, 1956. In June 1965 B-52s entered combat in Southeast Asia. By August 1973, they had flown 126,615 combat sorties with 17 B-52s lost to enemy action. The aircraft on display saw extensive service in Southeast Asia and was severely damaged by an enemy surface-to-air missile on April 9, 1972. In December 1972, after being repaired, it flew four additional missions over North Vietnam. Transferred from the 97th Bomb Wing, Blytheville Air Force Base, Ark., this aircraft was flown to the museum in November 1978. TECHNICAL NOTES: Armament: Four defensive .50-cal. machine guns in tail plus up to 43,000 lbs. of conventional or nuclear bombs Engines: Eight Pratt & Whitney J57s of 12,100 lbs. thrust each Maximum speed: 638 mph Cruising speed: 526 mph Range: 8,338 miles unrefueled Ceiling: 49,400 ft. Span: 185 ft. Length: 156 ft. 6 in. Height: 48 ft. 4 in. Weight: 450,000 lbs. maximum
I cut away about half the thickness of the cracked part. Made a collar that was a shrink fit, (The collar was several thousandths of an inch smaller than the part it was supposed to fit over.) Hot air gun warmed the collar and I used an upside down can of compressed air to chill the shaft then pressed the two parts together. I had left the collar over-sized. After it was shrunk on I trimmed it to match the original part. This minimized the possible duplication of errors that could happen if all parts had been cut to finished dimensions before assembly.
