Deployment/retraction mechanism for solar maximum mission high gain antenna system [PDF]

open access: yes, 1979
A mechanism called a deployment/retraction assembly (DRA) which provides not only a stable, but a deployable platform for the high gain antenna system (HGAS) aboard the Solar Maximum Mission (SMM) spacecraft is described.

Hoop/column antenna deployment mechanism overview [PDF]

open access: yes, 1985
The hoop/column antenna program is directed toward the development of a cost effective, large area, self deploying reflector antenna system. Large surface area antenna systems are required in future space missions involving improved land communications ...

Numerical-experimental static analysis of the effort of the crossbar-longeron in the semi-trailer frame [PDF]

open access: yesAIP Conference Proceedings, 2019
The article presents the verification process of a new type of transverse of beam semi-trailer main frame, as an element of the process of developing a new structural design. The main goal of the research was to determine the possibility of using bent sheet metal profiles as the transverse beams in the curtain semi-trailer frame.

Securing mechanism for the deployable column of the Hoop/Column antenna [PDF]

open access: yes, 1983
The Column Longeron Latch (CLL) was designed and developed as the securing mechanism for the deployable, telescoping column of the Hoop/Column antenna. The column is an open lattice structure with three longerons as the principal load-bearing members. It

THEORETICAL STUDY ON VIBROACOUSTICS UNDER DYNAMIC TEST FOR CYCLICAL STRENGTH

open access: yesВестник Донского государственного технического университета, 2018
The theoretical study on the excitation of the equipment vibrations and noise emission under the dynamic testing of helicopter longerons is resulted. The dependences for determining vibration spectra in the operating space are obtained.
