I have a feasibility study done on my personal dirigible, that shows that it is possible to build and fly a craft of my design. My plan is to have a sealed/pressurized crew compartment made out of carbon fiber that would have four hydrogen filled balloons for vertical take off & landing capabilities. These four balloons would be positioned with one on top of the crew compartment , one in front, & one on each side. Inside the balloons on the sides & front would be an extendable wing/spar structure to change the shape of the craft in flight to give it a more aerodynamic shape. With the intent to facilitate faster forward speeds than are currently available with ...


Planetary Rotor Engine Company (PREC) is a technology company formed to develop the Planetary Rotor Engine (PRE) -- a revolutionary engine design offering many advantages over the conventional piston driven internal combustion engines (ICE) that dominate engine markets today. With four rotors surrounding the center of the one chamber and turning in unison within a housing and end plates, a PRE provides great power density with very few moving parts. The others are the intake and exhaust valves plus the external gearing delivering power.

This novel engine configuration can reduce thermal losses and thus increase fuel efficiency. Friction, noxious emissions and probably ...

The invention outlines the design of a quad-tilt rotor that is implementable on a large scale UAV.

Design explanation:
As the present Aerospace industry is very much interested in VTOL designs, this design is primarily designed for that. To reduce the fuel consumption we used the tilt rotors i.e, the thrust required from each rotor while take-off is equal to one-fourth of the weight and after transition (in cruise flight) it will be only one -fourth of the drag.This decreases the fuel consumption a lot.

About the vehicle:
Most of the technologies to fabricate the device are in existence, and well understood.
General aerodynamic analysis for wing and whole design carried out using Finite Element Analysis method. Result ...

I have designed a quadcopter. I also have designed a lot of automobile components (ex: suspension gearbox, cvt, rollcage, eye joint ,ball join, knuckle,steering, etc). I have not gotten any coaching or professional help from any person. I have learned some things by youtube and lot of things myself.

A quadcopter, also called a quadrotor helicopter or quadrotor, [1] is a multirotor helicopter that is lifted and propelled by four rotors. Quadcopters are classified as rotorcraft, as opposed to fixed-wing aircraft, because their lift is generated by a set of rotors (vertically oriented propellers).

Quadcopters generally use two pairs of identical fixed pitched propellers; two clockwise (CW) and two counter-clockwise (CCW). These use independent variation of the speed of ...

Currently, CubeSats are launched into space using conventional rockets, which have to push through an extremely dense atmosphere and burn up a lot of fuel on the way up, subsequently raising the price on companies/organizations looking for a ride.

RALS, or Reduced Altitude Launch System, will be a reusable transport vehicle/platform capable of delivering CubeSats to a low earth orbit. This system will fuse multiple technologies together and will provide a cost effective solution for launching CubeSats to low earth orbit. Current weather balloon technology has proven to be a reliable and passive source of lift. Electromagnetic rail gun technology has proven to be a reliable and effective source of fuel-less propulsion. Gas-filled hollow I-beam technology and light weight ...

The invention outlines the design of a nano-size camera that is implementable on a nano-scale electromagnet. The camera is fabricated using the infrared photodetectors (semiconductors) that are designed on a sub-micron technology. (The camera is thus, an infrared camera, because the visible spectrum would be too complicated with the optical sensor fabrication.)

The exoskeleton (itself integrated electromagnetically charged) contains this nano-size camera. The exoskeleton is placed in a transparent accelerator, that could be made the size of a handheld device. Switching frequencies in tens of GHz may be used to accelerate the camera and electromagnet exoskeleton.

This device can then be used to collect infrared imaging data, while the data is being stored and/or transmitted. When the camera is ...

The Robotic Automated Erosion Coating System in production by AV&R Aerospace applies consistent and repeatable coating thickness to jet engine fan blades without leaving drips, inconsistencies and wasteful overspray, which are common quality issues encountered with current production methods. Uniform film build up and precise film thicknesses can be achieved within ± 2 thousandth of an inch with greater speed and productivity compared to manual operations.

In addition to increasing repeatability and productivity of our client’s plant, automation of coating applications ensures a better operation stability (consistent thickness, uniform application and consistent result over time), paint-spraying environment control (temperature, humidity, airflow and dust) and eliminates exposure to harmful chemical. Moreover, the system controls the chemical delivery in real time close ...

Mars offers an attractive first step for expansion into the solar
system and beyond. Offering a range of possibilities, Mars plays a
vital role in our future. Humans have not ventured into the extreme
deep space environment, as this hostile environment proves difficult
to overcome.

The proposed spacecraft, Solar Adaptive Gathering/Observation Nautilus
(SAGON), is a vessel designed for manned deep space exploration. The
initial purpose of the craft is for a mission to the planet Mars,
however it designed capable of traveling deeper into the solar system.
It is modular designed versatile enough to perform multiple missions
before needing to be retired. The ship is designed majorly off of
existing technologies, therefore less costs are associated with the
ship ...

Times have changed and information is king but an important area to understand our world is still shrouded in much mystery: remote sensing from satellites. SatNet is an online hub connecting end-users to EOS (Earth Observing System) satellites and information in an efficient, intuitive manner. Currently, there is no single site for satellite information that provides users with a direct connection to the information they need. SatNet will bridge this gap and facilitate this process for both novice users and experienced researchers. Our ultimate goal is to provide a “one-stop” website in which users can easily connect to databases and satellite information. SatNet will facilitate and highlight satellite services in academia, government planning, and recreation.

The EOS has provided ...

Thanks to its dramatic improvements in aircraft ground collision avoidance, this technology can save the lives of ~100 people each year in the U.S. alone by preventing what is called controlled flight into terrain (CFIT). Accounting for nearly 20% of general aviation deaths, CFIT occurs when a distracted or incapacitated pilot flies a fully functioning aircraft into the ground. A particularly noteworthy example of CFIT was the 1999 crash that killed John F. Kennedy, Jr.

Although CFIT warning systems are available to large commercial air carriers, they are too expensive to use in general aviation aircraft and are not appropriate for military fighter planes.

Fortunately, researchers at NASA Armstrong Flight Research Center have come up with a solution.
