Current autonomous drones for aerial sensing are often costly, heavy (typically over 500 g), and require licensed pilots under aviation regulations. This restricts their use for education, research, and small-scale field applications. LiSA UAV addresses this by offering a lightweight (d on a compact 2.5-inch cinewhoop carbon fiber frame. It supports multiple autonomous modes, including Loiter,
An Archimedes principle of buoyancy driven electrical energy generation system. The System comprises a wheel assembly which rotates within a water tank. The wheel assemblies outer structure has side by side internal concave partitions. Within these partitions, six sets of air bladders are housed.
In recent years, forest fires have increased dramatically in both frequency and intensity, posing a severe threat to human life, wildlife, property, and global ecosystems. Climate change, prolonged droughts, and expanding human settlement near wildland areas have significantly amplified the risk and consequences of wildfires. Traditional fire management and response systems are often reactive,
Controlled nuclear fusion for producing energy for civilian applications has been long awaited since the 1950s.
For technical reasons, current approaches are based only on Deuterium-Tritium reaction which produces 17.6 MeV.
The proposed development will allow to increase the efficiency of using energy of compressed air in piston motors for generating energy to move a vehicle or a stationary engine (with daily fluctuations in electricity consumption). The considered technical solution will contribute to improving the environmental and techno-economic indicators of piston motors when using compressed air in them.
GROWING lasers on silicon has eluded scientists for decades and has been referred to as the Holy Grail of photonics [1]. The fundamental issue preventing the integration of III-V based laser diodes on silicon (or other) substrates is the lattice mismatch between the material systems.
The "Rescue Hopper 911" is a VTOL thrust vectoring aircraft used for search and rescue missions. The Rescue Hopper is uniquely safe and low noise with an enclosed propeller system.
Helicopters and other multi rotor aircraft have dangerously exposed propellers that can cause a blade strike which can lead to a hard landing.
Each year, over 36 million falls are reported among U.S. adults aged 65 and older, leading to more than 32,000 deaths and over $50 billion in medical costs (CDC, 2023). A leading intrinsic cause is age-related hyperkyphosis, an excessive forward curvature of the thoracic spine, seen in up to 40% of older adults (Kado et al., 2004).
I have a patent application on invention "flying vehicle," declined on end stage. Ukrpatent said that Ukraine cannot create this project.
Atmospheric pressure 100 kPa. This is mean than in 1 square meter action force 10000 kilogram (kgs). I made experiment.
Overview:
Inspired by the adaptive and highly efficient flight of birds, BioMorph Wings is a revolutionary UAV wing design that mimics avian feather articulation to optimise aerodynamic performance across varying flight regimes. The system features modular, morphing wing surfaces composed of interlocking, bio-inspired, feather-like elements made of shape-memory alloys (SMAs) and ultra-light composite materials.
