Download or read book Lunar Orbiter Flight Vibration Data and Comparisons with Environmental Specifications written by Sherman A. Clevenson and published by . This book was released on 1970 with total page 76 pages. Available in PDF, EPUB and Kindle. Book excerpt: This paper presents detailed flight-measured vibration data obtained during the five successful flights of Lunar Orbiter and compares these data with vibration levels specified as flight acceptance requirements. Measured flight vibration data on these flights were lower than those measured on previous flights of the Atlas-Agena launch vehicle and thus the flight acceptance random vibration test levels substantially exceeded the flight measurements. This paper also discusses the derivation of the flight requirements.
