“…Among NEAs, those exploiting shape memory materials, including shape memory alloys [18] (SMAs), SMPs and SMPCs, have attracted much attention. The release devices based on SMAs [19,20] are ideal substitutions for explosive bolts with the advantages of repetition without deterioration and eliminating the volatile risk in storage and manipulations. However, their limited deformation capacity is a restriction.…”

Mars is believed to contain signs of the ancient life and to be the future of humankind. Deep space explorations on Mars have received extensive attention from the scientific and engineering communities. An ancient papyrus scroll-inspired mechanism to deploy the national flag after landing is proposed in this paper. Firstly, a papyrus scroll-inspired structure folded and deployed by shape memory polymer composites was designed. The material was characterised by both thermodynamic analysis and static mechanical tests. Then, computational modal analysis was completed with material parameters at 25 ℃, 55 ℃ and 85 ℃ to investigate the temperature effect. Besides, ground-based engineering validations were conducted, including vibration, shock and acceleration tests, as well as deployment verification. Natural frequencies obtained from vibration agreed well with that calculated from simulation. Regular and vacuum deployments showed differences but were both acceptable. Additionally, release reliability greater than 99.99% was obtained through repeated experimental data. Finally, on-Mars qualification was completed with China's Tianwen-1 mission, with images of the deployed five-star red flag transmitted by the Zhurong rover. It is the world's first validation of self-deployable mechanism based on shape memory polymer composites in deep space, and further applications can be expected.

“…[9][10][11][12][13] Separation mechanisms based on SMA offer simplicity, repeatability, adjustability and unique material characteristics. They have been used in aerospace 14,15 as an alternative to pyrotechnic separation devices. Moreover, SMA intelligent material replaces the pyrotechnic trigger or driving source.…”

To solve the problem of large operating noise of existing pyrotechnic separation devices, a new low-noise pyrotechnic separation device is designed by changing the utilisation mode of pyrotechnic separation, using micro gas pyrotechnic as heat sources, and shape memory alloy material to convert heat energy into mechanical energy. The results showed that the separation time was 1.526 s when the preload was 20 kN, and the maximum shock response was 319 G (2268 Hz) for 100 Hz–100 kHz. When used underwater, the maximum sound pressure level is 106.9 dB at 12,698 Hz and 98.5 dB from 10 Hz–5 kHz. Compared with a conventional separation nut, the frequency band sound pressure level can be reduced by more than 70 dB, realising underwater low-noise separation.

“…This situation motivates the developments of nonexplosive mechanisms for the picosatellite release and separation. [6][7][8][9][10][11][12][13] Poly picosatellite orbital deployer (PPOD), 14,15 JEM small satellite orbital deployer (J-SSOD), 16 and Tokyo pico-satellite orbital deployer (T-POD) 17 are well-developed deployers for picosatellites. However, they are all designed for single-use, none of which is resettable for multiple time deployments on-orbit.…”

The design, analysis, and test of the integrated device for the launch adapter and the resettable orbital deployer are presented in this paper. This integrated device contains both functions of the single-use launch adapter and the resettable orbital deployer. Two types of release mechanisms are combined. The four-bar linkage mechanism is applied in the single-use adapter function. This release mechanism provides sufficient strength of connection in the launch stage and is released when entering the orbit. The electromagnetic hook mechanism is applied in the resettable orbital deployer. The deployer can be reloaded by the manipulator on the mother satellite with picosatellites taken out from the cargo to deploy multiple times. Dynamics simulation, finite element simulation, as well as the prototype test verify the preliminary feasibility of this design.
