爆発：亜音速の燃焼と爆風（低グレードの爆発物） 爆轟：超音速の燃焼と爆風波（高グレードの爆発物） 爆燃の1例としては，山状にした黒色火薬に点火したときに起こる急速な閃光（爆発音なし）である。 1．はじめに. 爆発が恐れられるのは、ものが壊れるとともに破片が飛んでくることや、大きな音が発生すること、その音の原因となる爆風が周囲のものを壊すことでしょう。. 一口に爆発といっても、様々な種類に細かく分けることができます。. 爆発とは Image source: NASA. On the evening of Jan. 27, 1986, a group of engineers employed by rocket booster manufacturer Morton Thiokol pleaded against launching the Challenger space shuttle the next morning. The temperature at lift-off was expected to be no more than 26°F. The previous coldest launch, 53°F, occurred one year earlier with the space Emma Gibbs, 76, recalls the explosion Feb. 3, 1971, at Thiokol Chemical Corp. munitions plant in Woodbine, Georgia. Twenty-nine people were killed and more than 50 were injured. Gibbs was working at the plant there on Horse Shoe Bluff, making trip flares for U.S. Army troops to use in the Vietnam War. 1986年に起きたスペースシャトル「チャレンジャー」号の爆発事故は、なぜ起きたのか──。当時の関係者らの証言に基づいて悲劇の裏側を追った She wants young people to know about the people who died at Thiokol. So Gibbs helps Everette at the museum when she can. To anyone who asks, she tells her story. "It is a history that needs to be told for our country to really know itself," Gibbs said.
