NASA's Langley Research Center developed a deployable and stowable mechanical design for filling the cavity behind the leading-edge slat (i.e., slat cove), when it is extended upon landing an aircraft. Aerodynamic flow over an unfilled cavity typically exhibits strongly unsteady behavior that is a source of aeroacoustic noise. Conventional leading-edge slat devices for high lift are a good example of such geometric and flow conditions and are a prominent source of airframe noise. Experimental and computational results have shown that a slat-cove filler device could significantly reduce the noise produced by slat structures. The proposed structural concept will enable ...
Researchers at NASA’s Armstrong Flight Research Center have developed a new approach for putting satellites and other payloads into space that will revolutionize the commercial launch services market. Capitalizing on the advantages achieved by releasing payloads in midair rather than launching them from the ground, this unique approach uses a towed glider to put satellites into orbit efficiently, safely, and cost effectively.
Putting a satellite into orbit requires a lot of energy. Ground-launched rockets expend two-thirds of their propellant just to get through Earth’s atmosphere. Air-based launch is an option, but until now these methods have involved ...
It's a bird, it's a plane, or is that a man inside a Quad-copter Drone. First imagine what it would be like to fly. Then imagine a person wearing a quadcopter or quadcopter wearing the person. Also imagine what it would be like to have a guide with you wherever you go and who can actually listen. Then put those worlds together in harmony for a smart device you can wear. Once you put it on, you will be capable of low flight or high altitude travel. An A.Q.U.S. robot you can control, "well that sounds like a computer," ...
The lifting fuselage design has been around since the 1920's. It was shown by NACA (NASA) and through military competition in the 30's to be superior to the tube and wing design. Incorporating the most recent airfoil designs, composites and engine improvements, this design will easily cut in half the current airline fuel costs per passenger or pound of cargo. I believe it can out perform many of Boeing's BWB results. Versatility, flexibility and scalability make this design perfect for transport, cargo and tanker, military or civilian applications including unmanned aerial systems.
The simplicity of the design will cut costs ...

There is no global, mandatory reporting requirement for shipping containers lost overboard at sea. Obviously the companies responsible would rather not mention that they regularly drop containers into the world’s oceans.
Currently the World Shipping Council estimates that 2,700 shipping containers are lost at sea each year. Other sources mention a figure of 10,000. It is estimated that around 50% of these containers float on for anything from a few hours to (theoretically) indefinitely.
Keeping shipping containers onboard is rightly a major industry priority, but once one is lost overboard, for whatever reason, Containersinka is ...
A particle accelerator and containment vessel for anti-matter, specifically anti-iron.
The shape of the accelerator is that of a trefoil. An even distribution of particles along the containment path must be maintained. The total mass of the stream and its speed of traverse determine the strength and scope of the anti-Higgs field. Volume remains constant but mass is attenuated. As the field encompasses the trefoil, the trefoil becomes weightless.
The trefoil is necessary because the anti-matter must move through space equally in all three dimensions. A trefoil is the simplest structure that fulfills this requirement. ...

Imagine a world where outer space is not all that distant. It is a world where we all can take a spacewalk – not just a select few astronauts. It is a world where people travel from the Earth to Mars, maybe not regularly, but it’s as simple as booking a ticket. It’s a world where the resources of the solar system – and beyond – are available and used for the betterment of mankind. Perhaps most importantly, it is a world where humanity is not just one stray asteroid’s strike away from extinction, as we have colonies on ...
This technology will work on the principle of Action and Reaction.
MECHANISM:There will be two part of this engine.
The first part will move freely in a cylindrical tube but second part will be stable.
Two motors will be fixed in this engine as per the diagram. The (1) motor will work to press the first part towards the front side while (2) motor will work to press the second part towards backside. Two lever system will be attached with each motor.These levers will work to press their side springs when both motors will move.
There will be ...
Our Sirena Autonomous Underwater Vehicles - AUV / marine robot offer the ultimate in autonomous remote subsea survey capability. These free-swimming autonomous underwater vehicles are characterized by great maneuverability and high accuracy of stabilization. Hydrodynamic shape, accurate instruments and excellent battery capacity makes these AUV's ideal choices.
Sirena is available in several configurations and depth ratings. The main depth ratings are:
Because our HUGIN autonomous underwater vehicles can function without tethers, cables, or remote control, they have a multitude of applications in oceanography, environmental monitoring, and underwater resource studies. A key element ...
The field of Flapping Wing Micro Aerial Vehicles (FWMAVs) or commonly known as Ornithopters have seen a tremendous amount of research based upon an argument that they are more efficient than the traditional stationary wing or the rotary wing flight at smaller scales. Ornithopters emulate the natural flapping wing motion of birds and insects resulting in the flight. The presented work deals with the design and prototyping of the novel flapping wing mechanism for the Ornithopter in conjunction with the development of sophisticated system which can measure the flight parameters such as lift and thrust forces.
Intensive design ...
