“…Alongside orbital surveys, a suite of unmanned rovers with terrestrial, atmospheric, and/or oceanic capabilities have been proposed for investigations of extraplanetary bodies, particularly the large moons of Jupiter and Saturn. Airborne extraterrestrial vehicles, as first demonstrated by NASA's Ingenuity flights on Mars [44], have excellent potential for targeted planetary operations. For example, NASA's Dragonfly mission -due for launch in 2026 and projected to arrive at Titan in 2034 -will study the moon's atmospheric and surface properties, along with prebiotic chemistry in its subsurface oceans [21].…”

Aerospace technologies are crucial for modern civilization; space-based infrastructure underpins weather forecasting, communications, terrestrial navigation and logistics, planetary observations, solar monitoring, and other indispensable capabilities. Extraplanetary exploration -including orbital surveys and (more recently) roving, flying, or submersible unmanned vehicles -is also a key scientific and technological frontier, believed by many to be paramount to the long-term survival and prosperity of humanity. All of these aerospace applications require reliable control of the craft and the ability to record high-precision measurements of physical quantities. Magnetometers deliver on both of these aspects, and have been vital to the success of numerous missions. In this review paper, we provide an introduction to the relevant instruments and their applications. We consider past and present magnetometers, their proven aerospace applications, and emerging uses. We then look to the future, reviewing recent progress in magnetometer technology. We particularly focus on magnetometers that use optical readout, including atomic magnetometers, magnetometers based on quantum defects in diamond, and optomechanical magnetometers. These optical magnetometers offer a combination of field sensitivity, size, weight, and power consumption that allows them to reach performance regimes that are inaccessible with existing techniques. This promises to enable new applications in areas ranging from unmanned vehicles to navigation and exploration.

“…The detectors are expected to detect the unknown environment quickly and widely. Therefore, on the basis of the existing large detectors, it may be one of the effective schemes to carry several small detection robots with flexible movement and simple structures for the pre-detection of unknown areas [3,4].…”

Complex and unknown terrains in deep space exploration present great challenges to existing exploration robots. In this paper, a multi-mode motion spherical robot with flexible motion and strong environmental adaptability is presented. The spherical robot can roll and jump by swinging the pendulum and rotating the 2-DOF frame. The structure design of spherical robot is described, and the feasibility of multi-mode motion is analyzed by establishing dynamic model and testing robot prototype. In addition, the adaptability of the spherical robot motion mechanism in microgravity environment is preliminarily verified. The results of this analysis and test could be provided with reference for the future research of deep space exploration robots.

“…Electric propulsion is leading to a new focus in aircraft design due to the impact of green technologies on climate change. Moreover, drone flights through thinner atmospheres than earth's one are raising new challenges on what propeller propulsion can achieve [1]. These trends require the development of multi-disciplinary optimal propeller design.…”

Aircraft Propeller Design through Constrained Aero-Structural Particle Swarm Optimization

et al. 2022

An aero-structural algorithm to reduce the energy consumption of a propeller-driven aircraft is developed through a propeller design method coupled with a Particle Swarm Optimization (PSO). A wide range of propeller parameters is considered in the optimization, including the geometry of the airfoil at each propeller section. The propeller performance prediction tool employs a convergence improved Blade Element Momentum Theory fed by airfoil aerodynamic characteristics obtained from XFOIL and a validated OpenFOAM. A stall angle correction is estimated from experimental NACA 4-digits data and employed where convergence issues emerge. The aerodynamic data are corrected to account for compressibility, three-dimensional, viscous, and Reynolds number effects. The coefficients for the rotational corrections are proposed from experimental data fitting. A structural model based on Euler-Bernoulli beam theory is employed and validated against Finite Element Analysis, while the impact of centrifugal forces is discussed. A case of study is carried out where the chord and pitch distributions are compared to minimal losses distribution from vortex theory. Wind tunnel tests were performed with printed propellers to conclude the feasibility of the entire routine and the differences between XFOIL and CFD optimal propellers. Finally, the optimal CFD propeller is compared against a commercial propeller with the same diameter, pitch, and operational conditions, showing higher thrust and efficiency.
