Abstract

NASA mengajak desainer global untuk menciptakan Lantai Fleksibel yang kokoh guna mendukung transfer logistik antar Common Habitat di luar angkasa. Tujuan utama dari desain ini adalah meningkatkan keamanan astronot dan menjaga stabilitas Docking Adapter Multi Gravity Active-Active Mating Adapter (MGAAMA) saat digunakan dalam misi eksplorasi luar angkasa. Common Habitat dirancang untuk mendukung misi berawak hingga 1200 hari di Bulan, Mars, dan ruang angkasa jauh, dengan struktur inti berbasis tangki oksigen cair dari Space Launch System (SLS). Desain lantai ini terinspirasi dari mekanisme pipa geser pada payung, memungkinkan fleksibilitas dan kekokohan. Proses perancangan dilakukan menggunakan Autodesk Inventor untuk pemodelan 2D dan 3D, dilanjutkan dengan analisis elemen hingga (Finite Element Analysis) untuk mengevaluasi distribusi beban dan deformasi struktur. Simulasi pembebanan menunjukkan tegangan maksimum sebesar 46.477 MPa, jauh di bawah batas aman Yield Strength material Titanium (140 MPa). Sementara itu, deformasi maksimum sebesar 0.50741 mm terjadi pada arah Y, namun masih dalam batas yang dapat diterima dan tidak memengaruhi stabilitas struktur. Penelitian ini dilakukan di Space Center NASA dengan mengintegrasikan teknologi mutakhir. Hasilnya, desain Lantai Fleksibel ini memenuhi standar keamanan dan stabilitas, sehingga efektif digunakan untuk transfer logistik antar Common Habitat dalam misi luar angkasa.

NASA invited global designers to create a robust yet flexible floor to support logistics transfer between Common Habitats in space. The primary objectives of this design are to enhance astronaut safety and maintain the stability of the Multi Gravity Active-Active Mating Adapter (MGAAMA) during space exploration missions. The Common Habitat is designed to support crewed missions of up to 1200 days on the Moon, Mars, and deep space, with its core structure based on liquid oxygen tanks from the Space Launch System (SLS). The floor design is inspired by the sliding pipe mechanism of umbrellas, allowing for both flexibility and robustness. The design process utilized Autodesk Inventor for 2D and 3D modeling, followed by Finite Element Analysis (FEA) to evaluate load distribution and structural deformation. Load simulations revealed a maximum stress of 46.477 MPa, well below the Titanium Yield Strength of 140 MPa. Meanwhile, the maximum deformation of 0.50741 mm occurred in the Y-direction, remaining within acceptable limits and not compromising structural stability. This research was conducted at NASA’s Space Center, integrating cutting-edge technology. The results demonstrate that this Flexible Floor design meets safety and stability standards, making it an effective solution for logistics transfer between Common Habitats during space missions.
