Our electromagnetic variable flow control valve is a very efficient, cheap to make, reliable and provides an outstanding performance including instant response and fail-safe mode which are critical for fuel systems of unmanned autonomous vehicles (UAV) powered by jet, diesel, diesel-gas and other types of engines using fluidic fuels.
There are three main systems for variable control of fluid flow currently available to the market: a) modulated solenoid valves, b) needle spool valves and c) rotational valves with different types of actuation. Bulky design, slow response, complex electronics, parts’ wear and inconsistency of the output can be main ...
The design presented is based on the continued need for providing structural elements in space at optimum cost, appropriate utilization and reutilization. This concept describes a simple flanged beam with interlocking edges. When placed together, the geometry results in a cylindrical structure that, as shown in the drawings, provides the main section of an unmanned space craft.
This cylindrical structure is topped with an instrument and aerodynamic cone and fitted to a propulsion unit at its base. Once at the prescribed destination, the cone and propulsion units are removed. The compression bands are separated from the cylinder and the ...
Problem: It takes a lot of manpower to search an entire nation for weapons of mass destruction, as we learned in the Iraq War.
Solution: Have a swarm of robots lend some extra hands. Imagine a chassis mounted with a Geiger counter (for nuclear weapons), chemical residue sensor (for chemical weapons), pathogen sensor (for biological weapons), GPS receiver, wireless communication, single-chip computer, and solar panel. As a robot sweeps a designated region (so as to not overlap with what the other robots are doing), the Geiger counter, chemical residue sensor, and pathogen sensor will wirelessly communicate their readings to ...
Ducted Fans have been used in a wide range of vertical take-off and landing (VTOL) aerospace vehicles, including manned and unmanned systems. This paper focuses on performance improvement of ducted fans in forward flight applied to VTOL UAV and Tiltrotor aerial vehicles.
The concept proposed is called Ring Wing Ducted Fan (RW-DF). It is the combination of two concepts, the ducted fan and the ring wing technology.
Ducted fans have several advantages compared to open rotors and fixed wing airplanes. They provide higher thrust to power ratio, improved safety and lower noise levels for a given diameter when ...
With specimen of sea ships it is necessary to apply in planes modular construction of the passenger cabin. Everyone should have a module castle enabling the hermetic sublation from the rest of the plane. In case of the breakdown of the plane pyrotechnic cargoes should separate the module from the plane. The module should land safely with ...
This project focuses primarily on the Sailfish Aerodynamics. The idea is to use the shape of the sailfish in a hybrid energy aircraft. The Sailfish (Istiophorus platypterus) is the fastest fish in the world with a speed of 68 mph (108.8 Km/h). Its body has a unique shape which is the lowest drag producing shape in nature. The conclusion was reached by observing the other high speed fishes - Marlin (50 mph) and Swordfish (60 mph).Conventional passenger aircraft use a round-body fuselage, which reduces the efficiency and causes noise pollution. Though developments in reducing the drag induced by the ...
Robot is a machine to execute different task repeatedly with high precision. Thereby many functions like collecting information and studies about the hazardous sites which is too risky to send human inside. Robots are used in different types like fire fighting robot, metal detecting robot, etc. Humanoids are robots which resembles human joints. Humanoids are nowadays used in industrial purpose, military, research etc.
With the improvement in research and development in robotics, they have started serving the so called three D’s, dull, dirty and dangerous, quite efficiently, thus providing extended standoff and reducing risk of exposure. This ...

Two-dimensional detector arrays of thermal infrared imagers are expensive, especially at medium and high resolutions. A 10,000 pixel imager costs about $1,600. An 80,000 pixel device costs about $5,500, and an imager with near 3x105 pixels costs about $20,000. Now assume that, instead of the bolometric arrays of present thermal imagers we place a thin, strongly fluorescent film in thermal contact with the infrared-absorbing layer and illuminated from the sides to excite the fluorescence of the film in such a manner that the infrared image focused on it will be converted into a corresponding visible image at the film, ...

The structure of a spacecraft is designed to support the maximum quasi-static loads (accelerations) that it will be subjected to during its launch phase. These loads are a combination of the steady-state static loads and low frequency sinusoidal loads.
Quasi-static loads can be used to dimension the spacecraft, provided the minimum frequency requirements with respect to mode shapes in the launch direction and the lateral direction are fulfilled.
The estimated mass distribution times the quasi-static loads gives the internal loads distribution within the spacecraft structure. These internal loads can be used to obtain the preliminary dimensions of the spacecraft structural elements. ...
PRODUCT: SKILL CAPACITY© is a user-customizable, mobile skills assessment and performance evaluation “template” that will provide any DoD/SOF training program, skills evaluation program, etc., with the ability to identify, define and grade tangible fundamental skills (PST), advanced technical/tactical/physical (motor, psycho-motor) skills or the intangible and or, cognitive, learned, subjective/behavioral requirements that instructors observe during training exercises.
RESULTS: The results of this disparate data collection activity can be stored in a highly secure multi-layered database and used for extensive predictive analytical analyses and data mining to aid in reducing risk associated with SOF candidate selection/evaluations, and contribute to specific accession/performance ...
