Encore un grand moment d'humanité
Ah oui, je m'en souvient maintenant. Mais je n'avais pas compris ce qu'il y avait derriére le mot "fuel" dans cette arme.
"fuel" en Anglais est un faux amis qui signifie pas le fuel de chez nous qu'on met dans la cuve de la maison, mais <<combustible>> en géneral.
Donc d'aprés toi ca serait du propane, mais j'ai trouvé "Ethylene oxyde" également.
je pense que tu as trouvé les infos sur :

Fuel-Air Explosives [FAE] disperse an aerosol cloud of fuel which is ignited by an embedded detonator to produce an explosion. The rapidly expanding wave front due to overpressure flattens all objects within close proximity of the epicenter of the aerosol fuel cloud, and produces debilitating damage well beyond the flattened area. The main destructive force of FAE is high overpressure, useful against soft targets such as minefields, armored vehicles, aircraft parked in the open, and bunkers.
Fuel/air explosive represent the military application of the vapor cloud explosions and dust explosions accidents that have long bedeviled a variety of industries[
TNT generates well over 4,000 psi overpressure in close proximity to the source of the explosion, along with significant radiant heat effects from the explosion's fireball. Conventional high explosive munitions also produce fragments from the munition case, as well as fragments from material in the target area that is broken loose by the high blast overpressures.
There are dramatic differences between explosions involving vapor clouds and high explosives at close distances. For the same amount of energy, the high explosive blast overpressure is much higher and the blast impulse is much lower than that from a vapor cloud explosion. The shock wave from a TNT explosion is of relatively short duration, while the blast wave produced by an explosion of hydrocarbon material displays a relatively long duration. The duration of the positive phase of a shock wave is an important parameter in the response of structures to a blast.
D'aprés ce que je comprend, une telle bombe produit une onde de choc plus longue que pour une explosion au TNT, mais peut étre d'une puissante instantanée moindre.
Brrrrrr
et l'armée US a déja decliné 5 types de bombes sur ce principe : les BLU-73, BLU-95, BLU-96, CBU-55, CBU-72
et c'est pas nouveau : a été utilisé au Vietnam et pendant la 1ére guerre du golfe.
CBU-72 / BLU-73/B Fuel/Air Explosive (FAE)
The the 550-pound CBU-72 cluster bomb contains three submunitions known as fuel/air explosive (FAE). The submunitions weigh approximately 100 pounds and contain 75 pounds of ethylene oxide with air-burst fuzing set for 30 feet. An aerosol cloud approximately 60 feet in diameter and 8 feet thick is created and ignited by an embedded detonator to produce an explosion. This cluster munition is effective against minefields, armored vehicles, aircraft parked in the open, and bunkers.
During Desert Storm the Marine Corps dropped all 254 CBU-72s, primarily from A-6Es, against mine fields and personnel in trenches. Some secondary explosions were noted when it was used as a mine clearer; however, FAE was primarily useful as a psychological weapon. Second-generation FAE weapons were developed from the FAE I type devices (CBU-55/72) used in Vietnam.
Bon, ben passez un bon Dimanche paisible quand méme si ceci ne vous à pas cassé le moral.
