为美国空军研制的导弹整体级方案(ISC),采用一般的结构件将两级火箭发动机组合在一起,从而提高了多级导弹系统的性能,使现有推进系统体积得到更有效的利用,并能得到更高的发动机可靠性和明显地降低制造成本。在以往的几年中,航空喷气战略推进公司(ASPC)曾经研究将整体级方案应用到采用部件设计概念和新材料的几种未来系统上。近期完成的详细研究表明,对于限定体积的系统级性能约提高30%和限定重量的系统级性能约提高15%。本文概述了这些系统的研究结果,所介绍的一些特定系统包括:先进的洲际弹道导弹,空中发射的助推滑翔飞行器,速燃助推器和轨道转移飞行器。最后,讨论了整体级降低成本预估的基础和将来发展的计划。
The Integrated Missile Program (ISC) developed for the U.S. Air Force incorporates a two-stage rocket engine using common structural elements to improve the performance of the multi-stage missile system and make the volume of the existing propulsion system more efficient and Can achieve higher engine reliability and significantly reduce manufacturing costs. In the past few years, ASPC has studied the application of a monolithic solution to several future systems that employ part design concepts and new materials. Recent detailed studies have shown that about a 30% increase in system-level performance for a limited volume and a limited weight of about 15% increase in system-level performance. This article provides an overview of the findings of these systems. Some of the specific systems introduced include: advanced ICBMs, airborne propellant gliding aircraft, quick fire boosters and orbiting vehicles. Finally, it discusses the basis for overall cost reduction estimates and plans for future growth.
