GIMBALS FOR VECTOR CONTROL OF NERVA LIQUID MOTOR TRANSPORTERS
Journal Title: ROMANIAN JOURNAL OF TECHNICAL SCIENCES - APPLIED MECHANICS - Year 2009, Vol 54, Issue 3
Abstract
The team for space technology of UPB presents the project for achieving a proprietary orbital access launching system under the NERVA readiness opportunity. The NERVA vehicle is a readily available and low cost means to demonstrate the feasibility to achieve secured high altitude sub-orbital flights with a final delivered velocity of one half the orbital velocity at 100 miles altitude, a typical low Earth orbit (LEO), by the conversion of dismissed soil-air SA-2 Guideline systems. These weapons became obsolete recently in Romania. The main technological feature regards the gimbal-type support of the rocket motor, presently within a fastened mounting. The problems arouse by the spherical bearing and its controls are revised in the paper. Application focuses on the mechanics of the motor.
