The boundary-layers that occur on wings of flying aircraft have both laminar and turbulent-flow regions. Laminar-flow starts at the leading-edge and is felt on the forward part of both wing surfaces. Depending upon the local Reynold's Number, the degree of free-stream turbulence, the surfaces’ curvature and their roughness, the boundary-layer flow will eventually change to being turbulent. The skin-friction drag of these surfaces depends on the way that boundary-layers grow and transit. The turbulent boundary-layer causes the greatest amount of local skin-friction and the postponement of the transition region to aft locations on both surfaces is a useful way ...

LunarSail is a cubesat-based space mission established by the Aerospace Research & Engineering Systems Institute, Inc. – a 501 (c)(3) tax-exempt non-profit organization dedicated to promoting space exploration and STEM education through hands-on educational projects and public outreach. LunarSail is designed to use a solar sail to propel a small spacecraft from Earth orbit onto a lunar orbit rendezvous trajectory and execute orbital insertion around the Moon.
LunarSail is an effort to demonstrate the ability of a spacecraft under solar sail propulsion to navigate itself into a lunar trajectory and insert itself into Lunar orbit. A primary objective of ...
Satellite imagery has proved invaluable in the defense and intelligence sectors. Furthermore, it has been an equally potent resource in such important commercial areas as land and water asset management, weather prediction, and geological and agricultural prospecting. One obvious difficulty that has quickly become apparent in all these applications is that it quite impossible for humans to adequately review such imagery, and to process and disseminate the useful data that can be extracted from it. We propose to combine the latest developments in machine learning with physics based modelling to create a universal, automated algorithm to provide robust analysis ...
MANTARAYA Delta Challenger
Military & Rescue, missions.
MANTARAYA Delta Challenger is an only underwater propelling device, because the diver stays in the wake of that device without pointless efforts, reducing air consumption and turbulence.
THAT BI-TURBO SYSTEM improves the hydrodynamic coefficient of penetration [Ch = Rv= Cv.(Re.K/L)], saves energy, increases the velocity and the autonomy. In addition the maneuverability is exceptional.
MANTARAYA Delta Challenger is an adaptation of the original work MANTARAYA, created in 1992. That only symbolic “Art & Technique concept” insures the visibility on the market place and the worldwide protection according to the Berne Convention.
APPLICATIONS: Military & Rescue, ...

The Mars Biodome is a dome made out of transparent tri-layered panels and a sturdy frame that allows people to live on Mars. The panels on the Biodome are made of glass on the inside, a glass-plastic-glass layer on the outside, and a gas called argon in between to help with insulation. The glass-plastic-glass layer will be extra durable should dust or space debris end up hitting the pane. Having a piece of plastic in between the two outer glass panels helps keep the panel from shattering even if it cracks. The panels will be polygon shaped, most varying ...
We propose here the application of Micro-Electro-Mechanical Systems (MEMS) as part of a science surface properties package aboard a future Lake Lander. MEMS devices offer a low cost and reduced size of instrumentation in order to accomplish the 3-D sounding of the liquid deposit and detect the presence of any biomarkers in a broader area.This deployment will provide a broad network of surface and submarine IR and RF sources, while the signal receiver sensor will be aboard the Lake Lander. The MEMS micro-probes will follow the swarm pattern in which each apparatus single operation is a component of a ...
Space exploration is EXTREMELY EXPENSIVE. We live in the deep valley of Earth’s gravitational well. Very large rockets are required to put small payloads into space. Launch mass must be reduced to create a sustainable future in space. A large fraction of spacecraft mass is propellant for in-space propulsion. Large reductions in launch mass will come from production of in-space rocket propellant from in-space water. Vast quantities of water are present at the lunar poles, on Mars, comets, and some asteroids. Using the in-space resource, solar energy, in-space water can be split into hydrogen and oxygen for propellant. Molecular ...
Satellites in Earth orbit are increasingly in danger of being damaged and disabled by collisions with orbiting pieces of debris that are generated by explosions of fuel tanks or other mishaps, etc. These collisions generate more debris, which will eventually - over thousands of years - burn up in the atmosphere. In the meantime, a runaway cascade of debris generation can occur, as predicted by Kessler in 1991  ("the Kessler syndrome"). There is widespread agreement that at orbital heights near 1000 km and 1500 km altitude the critical density for such a runaway process has already ...
Unmanned Air vehicle or uninhabited air vehicle (UAV) is essential equipment that is used in military warfare. However, owing to its large size, it is easily detected by the enemy causing it to be vulnerable to enemy counter attack. Micro Air Vehicle can be considered as a superior alternative to the UAV. The size of an MAV is in the order of few centimeters and cannot be detected by the human eye easily. Also, it can fly alongside human beings, whereas the UAV can only hover above a region.
In the present paper, an innovative project for design ...

My Multistage Jet Engine design is like two or more combustion chambers or combustors connected in series, each combustion chamber or combustor represents 1 (one) stage each whose fuels combust all together at the same time so that the velocities of the combusted gases are amplified by providing the combusted gases an initial velocity equal to the velocity of the combusted gases that are pushing their way through from the previous stage. The total thrust of the engine is equal to the sum of the combusted gases that are exiting through the mouth of the combustor's nozzle whose velocities ...
