This entry focuses upon the process of rotor balance. The term rotor refers to the type found in jet engines. During the engine assembly process, rotors must be balanced to a very high level of precision. Rotors are typically balanced by using a device called a balance machine. If a rotor is not properly balanced, the engine will vibrate in the field (i.e. on-wing). Vibration causes efficiency loss and undesirable engine wear.
Data shows that rotors which achieve a passing score from a balance machine are not necessarily going to pass in the field. There are external inputs that ...
I am presenting a design of a very unique ROVER which is based on inchworm motion. It will move like an INCHWORM using its telescopic arm and suction system. The rover will get energy from solar cells.
There are two parts to this rover, a front and a back part. Both parts will be connected to each other. Each part will have a motor, a wheel and a suction system. At the time of motion the rear part will stick to the surface and the front part will move forward using its telescopic arm. After getting a certain distance, ...
The VForce® invention is a major evolutionary step in fixed wing aircraft development. High lift devices (flaps/slats) have not significantly changed since the invention of the Fowler Flap by H D Fowler in 1924.
The invention provides a lighter, less complex high lift device deployment mechanism that does not require under wing fairings and reduces fuselage shock body size all combining to reduce parasitic drag. Cruise flight drag is reduced and therefore less fuel is carried and consumed allowing for a higher pay load or increased range while providing a reduction in greenhouse gas emissions.
The VForce® invention also allows for ...
Despite its appearance as a barren, hard vacuum, Low Earth Orbit (LEO) has a very precious resource: Earth’s atmosphere. The atmosphere does not end at the official boundary of space (100 km) but grows increasingly rarified to an altitude well beyond that occupied by the International Space Station. At 180 km, there is a thin mixture of nitrogen, oxygen, and rarer elements. As liquid oxygen (LOX) and nitrogen tetroxide (N2O4), these elements constitute the majority of any deep-space mission’s initial propellant mass.
With a frontal area of 100 m2, a spacecraft orbiting at 180 km collides with 13,500 kg ...
The principles used in a polywell fusion reactor can also be applied, and more readily, for an electron-positron antimatter collider/reactor. Polywell fusion reactors make use of the principle that electrons require much smaller magnetic energy density in order to be magnetically confined than more massive ions. However, this principle applies equally to positrons. Thus, the application of the polywell approach to electron-positron reactions instead of fusion reactions has the advantage, that all of the fuel particles can be effectively confined within the magnetic fields, and the electric fields don't have to contain an ion plasma. Furthermore, positron-electron reactions are ...
A new image processing technology, nearest neighbor deconvolution (US Patent 7912307), is able to enhance image spatial resolution beyond the diffraction limit.
This technology rewrites the point spread function (PSF) with nearest neighbor model, applies the Shift Theory in Fourier domain, and achieves higher resolution images with inverse Fourier Transform.
This technology is able to:
1. Dramatically reduce weight of imaging satellites.
2. Enable small aperture cameras to reach resolutions as high as large aperture cameras.
3. Find more details from existing images.
Feasibility of this technology was approved by experiment, and by applying it to several NASA space ...
By 2050 it is estimated that 68% of the world's population will live in cities. This will cause even more traffic in cities, a big problem especially in those cities that already have huge traffic problems with no infrastructure to fix these issues. New creative methods will be needed to solve the traffic dilemma. One solution that would not involve adding much infrastructure would be utilizing a third dimension. A vertical takeoff and landing (VTOL) tail sitter aircraft would make use of this third dimension and create an upward outlet for some of this traffic. Eventually, the commute in ...
FLYING APPARATUS WITH FLEXBILE SHELL AND COANDA -EFFECT
Based on the Invention Patent No. 00121196, CLASA B63H9/04 from 06.12.2006 and Patent application(pending) A/00878/2017 from 26/10/2017
The technical solution is based on a flight apparatus with flexible outer shell, powered by the pressure effect described as the Coandă-Effect, apparatus built as an experimental model for functional tests.
Lenticular vehicles with Coandă Effect are an innovative solution for all flying apparatus with vertical take-off, high-speed flying apparatus, or the ones which require a robust and compact body – reentry body – at high altitudes and high speeds, but also are suitable for water (under ...
Electromechanical actuators are small and light devices that play important roles in aircraft control systems converting electrical energy into mechanical movement and can achieve high dynamic forces. Some applications correspond to landing gears, wheel brakes, spoilers, doors, and flaps. They are indispensable in aircraft operations are compact and light weight.

Currently, there is a lack of unmanned aerial vehicles that are being used with the purpose of extinguishing fires. An unmanned aerial vehicle (UAV) is an aircraft without a human pilot on board. Its flight can be controlled autonomously by computers in the vehicle, or by remote control under the direct command of a human. In the United States and the rest of the world, most of the UAVs in existence are being used for defense purposes.
Fires that occur in homes and non-residential buildings as well as fires in wild lands cause plenty of health issues; including death ...
