“…Controlled by the lanyard and motor fixed on the end plate, the coilable mast can deploy by steps. A tension sensor, installed on the lanyard, measures the deployment forces generated by elastic energy of the longerons and battens [4] . A accelerometer, installed on the turntable, measures the turntable's acceleration generated by deployment impact.…”

BUAA Student Micro-satellite (BUAA-SAT) is a gravity-gradient stable satellite depending on a coilable mast. The mast , used as the main deploying and supporting members, plays an important part on the whole satellite structure. What's more, deployment test and modal parameter identification results are two important factors of the deployable space mast. This paper describes deployment test and analysis of the mast, gains modal parameter results through the software Patran and Nastran. Compared to the test with hammering method, the models correlate with test data for low frequency modes, but fall short for higher modes. Through this new method, we find a solution to test large masts with very low first frequency.

“…Deployable mast structures have also been used extensively over the years. Some of the most reliable have proven to be tubular booms and coilable masts 4 . It is anticipated that as spacecraft continue to be developed with an increasingly diverse level of functionality, the demand for novel deployable architectures will increase.…”

A solar sail concept has been developed from a common spiral fold pattern in order to enable a simultaneous mast and sail deployment. This novel concept utilizes the stored strain energy in a series of elastic spar members to enforce proper folding kinematics rather than relying on bulky mechanical joints. The critical inner and outer spar networks are secured to four elastically extendible masts anchored to a central drum. Deployment of the solar sail system is actuated by rotating the central drum around which the masts, spars, and film are wrapped. Tensioned radial cords deterministically unfold the membrane film under the authority of the resilient, spring-like spar members. Proper elastic behavior of the spars is an important facet to this design, and thus a significant effort was dedicated their development. This compact ground demonstration concept includes about 7.5 m 2 of reflective membrane film for useful propulsion. Features of this robust, lightweight membrane structure may prove valuable to reducing mass and increasing deployment reliability of other planar subsystems such as sun shades, solar arrays, radiators, or antenna arrays. Nomenclature L= Side length of polygonal drum R = Drum radius h = Wrapped height n = Number of gores s = Characteristic length of one sail side w = Peak fold shifted distance α = Interior angle of polygonal drum

“…It is mainly used for extending flexible solar array and supporting deployable antenna, synthetic aperture radar and space telescope. Tubular boom, telescopic mast, coilable mast and some articulated masts have been developed and applied in outer space [1]. With the development of aerospace exploration, earth observation and military reconnaissance, the requirement for its specific stiffness, specific strength is stricter and stricter.…”

The design of a triangular prism modular deployable mast applied in outer space is introduced in this paper. Its configuration with high efficiency of stowage and locked pattern is proposed. Operating principle of the mast is raised as well. The geometry characteristics are discussed and its maximum possible folding ratio is analyzed in detail. The kinematics equations of any point on the mast are established and its deploying process is simulated to understand the regulation during deploying. The statics relationships between linkages and diagonal wires are discussed in detail. The expressions of statics parameters such as axial stiffness, bending stiffness, trosional stiffness of the deployable mast are constructed. The changing regulation of stiffness of the mast with its geometry parameters is analyzed, concluding the triangular prism modular deployable mast has a high stiffness and can be applied in space exploration.
