A Novel High Efficiency Variable Inlet Area Propulsor

The aircraft industry continues to search for a single aircraft capable of both high-speed cruise and efficient take-off and landing. Yet nearly all propulsion systems with nacelle inlets that fly today operate in a compromised state with at least one important flight condition existing in a sub-optimal state. In low speed flight, the inlets are often too constricted, in high speed flight, spillage often occurs. Thomas International, Inc., proposes a solution to the problem caused by the conflicting needs of highly efficient low speed lift related to propulsion versus efficient high-speed cruise with minimum spillage drag cruise with advanced technology propulsion units, the adjustable size inlet system, ASIS.

The ASIS propulsion ...

The planet is getting warmer day by day. Most climatologists regard the final decade of the twentieth century as the warmest in the past millennium. Even minor alterations in global temperature will trigger a series of weather extremities and alter the climatic patterns of the planet. Global warming effects on earth are caused by several factors. To understand the overall effects of global warming on earth, we have to understand the contributions and effects of each component of the planet. The gases produced from vehicles, power plants and other sources are building up in the atmosphere, acting like a thick blanket over our planet. It has been clearly identified that additional effective technologies are needed to control CO2 in ...

Although various three-dimensional technologies have been developed in recent years, few are able to display real time 3D images and video from any angle in the same way an object would appear to us in the real world. The new concept is a true three-dimensional display that allows users to view moving objects from any angle with the unaided eye, simply by walking around them as you would if you were looking at real 3D objects. I have invented a 3D Volumetric Display with clear picture and super clear depth; it has a 360 degree horizontal and 270 degree vertical viewing angle. New 3D volumetric display is entirely different from existing 3D TVs which produce translucent images even if ...

For decades work has been carried out to build robots similar to the human body structure but for this purpose a number of complex mechanisms are used. This new concept showcases a simple replication of human structure without a complex mechanism. This can be done with the help of a number of recent technologies like 4D printing, self-assembly, programmable matters and advancement in MEMS.

Recently researchers have made various self-folding sheets, self-assembling robotics block, shape changing materials with external stimulus. This advanced humanoid can be made combining all of this research. The basic principle is to use self-transforming materials at the position of human joints thus leading to similar motion as that of humans.

This ...

Reduction of size and weight and increasing efficiency is of paramount importance to maximize transmission efficiency. In order to make continuous speed ratios and thereby increase efficiency, I have successfully developed a new concept Continuously Variable Transmission after spending several years to research.

Advantages are Compact size, Very low frictional losses, Less maintenance due to the fact that there is less abrasive loss because of the less frictional losses, Very high input output ratio spread within very compact size for a CVT, it is of very less weight and compact size (resulting in better packaging of vehicle).

In this new concept CVT transmission of power is not by friction (as in conventional CVTs) in that case slip can ...

The present invention achieves the delivery of selected oxygen percentages as chosen by the health care practitioner as required, governed by blood gas analyses and or oxygen data via pulse oximetry. In addition to the above an immovable ceiling for oxygen concentrations is achieved by the selected health care practitioner, such that any impediments in flow or volume exchanged by the user and or patient with the incoming and or exiting gases cannot be reflected back upon the jetted Venturi valve, as current devices do. Such known reflected flow and or volume which is known in physics and respiratory medicine as “Venturi stalling” is thus completely removed by the present invention, thus preventing inadvertent hyperoxia periods common to the ...

Climbing robots have been developed and are in use presently. But most of them have been designed and developed for climbing man-made structures such as vertical walls, structural frames and glass windows. Few climbing robots have been designed, for climbing natural structures such as trees, especially coconut trees for harvesting coconuts in specific. This paper proposes the design and development of a robot prototype A.R.C.H-1, with a novel idea of climbing, maneuvering and fastening mechanism, that actually climbs effectively and efficiently a pole, which simulates a coconut tree by its varying diameter and rough uneven surface. This robot operates by the reception of command from operator on the ground and he can view and select the coconuts to be ...

Device for carrying mobile advertising images in subways

Therefore: it is considered as if it projects a series of images with a bright optical device mounted on a moving body, those images accompany the body to the velocity of same body (vehicle).

Train moving in a tunnel can carry a projection device, like projectors in cinemas, but smaller at and much lower cost. It will be mounted on the side of the train to direct the flow of light through the tunnel wall. The projector can output video (like a movie) or still images (like a slide projector). A second option could be considered more financially advantageous and easier to put into practice. We can imagine a picture that will ...

My name is Saugat and I am from Nepal. My project entitled “Modification in aircraft wing to increase lift” is theft from the engineering of nature seeing birds flying around the sky. Like humans, birds are the perfect engineering creation of nature.

While trying to think about the modification in the aircraft wing I thought about the bird's wings and developed a similar structure. I found out that the lift produced by such wings are better than the wings that the recent aircraft use. It’s because the highly pressurized air below the surface of the wings gets less area to give the lift force. As a result the overall lift increases. Using this mechanism we not only ...

The Aerospace Integrated Bearing is a design that can only be fabricated by additive manufacturing and which exploits most of the benefits of this technology.

We have created an optimized and customizable support for space that can rotate in the 3 axes and it can be manufactured ALL in just 1 step. It does not need any assembly and still contains a ball-bearing inside the support.

The application of this design is a mechanism to orientate the solar panels of a satellite.

Current supports in most satellites only deploy the panels to a fixed position with a hinge mechanism. We performed a holistic approach addressing structural integrity, functionality, material, energy consumption and assembly simplicity to ...
