عنوان انگلیسی: Status of Ramjet Programs in the United States عنوان فارسی: وضعیت برنامه های رمجت در ایالات متحده رشته : مکانیک، هوافضا، برق تعداد صفحات مقاله اصلی: 10صفحه (pdf) تعداد صفحات ترجمه:26صفحه ( word ) سال انتشار:2008 مجله 44th AIAA/ASME/SAE/ASEE Joint Propulsion Conference & Exhibit 21 - 23 July 2008, Hartford, CT Abstract: At present, the US military services are focused on networking, battlefield communication, and targeting using existing weapon systems. As such, there is little effort directed toward the development of new weapon systems, but rather, improvement programs for existing missiles as the need dictates. As the situational awareness improves, the need for faster, long range missiles will be ...
عنوان انگلیسی: Boron Carbide Combustion in Solid-Fuel Ramjets Using Bypass AIr. Part I: Experimental Investigation عنوان فارسی: احتراق کاربید بور در رمجت های سوخت جامد با استفاده از هوای کنارگذر (بای پس). بخش اول: بررسی آزمایشگاهی رشته : مکانیک، هوا فضا تعداد صفحات مقاله اصلی: 6 صفحه (pdf) تعداد صفحات ترجمه:19صفحه ( word ) سال انتشار:1996 مجله Propellants, Explosives, Pyrotechnics 21, 289-294 (1996) Abstract: The effects of bypass air on the combustion of highly loaded boron carbide/HTPB fuel grains in a solid-fuel ramjet motor were investigated experimentally. It was found that combustion efficiency can be significantly increased by employing high bypass rations with low dump momentum. The results indicated that high bypass dump momentum causes the particles to collide with the wall and extinguish. Increa ...
