As the core of a modular, optionally-manned, single-stage-to-orbit, reusable, trans-atmospheric spaceplane; this combined-cycle engine which operates on JP-7 jet fuel, and either air or LOX; functions as an Expansion-Cycle Turbojet for takeoffs and landings (for noise reasons).

The outbreak of the new Sars-CoV-2 virus 2019 posed and still poses new challenges for us. For many, it is the first pandemic they have experienced. To prevent future outbreaks and the impact of viral infections we are developing ComImmunity.

This "Shimmer" technology is designed to be incorporated into vehicles in order to decrease the possibility of chain rear end accidents. A common traffic scenario involves a leading vehicle (#1), a first trailing vehicle (#2), and a second trailing vehicle (#3).

Solar trackers have been used for decades. Trackers aim solar panels to continuously face the sun to maximize the energy captured. Concentrated photovoltaics (CPV), like conventional photovoltaic systems, generate electricity from sunlight. Compared to conventional photovoltaic systems, CPV are more efficient.

Below is the equation for the resistance of a fluid flow system:
∆P/Ǭ=(q-W)/VǬ-ρ δv/Ā-(μA_⟘ dv_⟘)/ĀǬ-(ρA_h gδh)/ĀǬ
Where Ǭ is the total volumetric flow in the system; ∆P is the pressure difference across the system; V is the volume of the system;

The screen of this device is normally in a passive flight following mode showing aircraft position, flight plan route, weather and terrain/obstacles.

The system calculates a predicted flight path. If the predicted flight path detects a potential CFIT situation,

The recent coronavirus outbreak worldwide created an emergency involving all countries In order to help fight the virus one of the most important early activities is to detect potential carriers through the body temperature monitoring, by individuating those with body temperatures higher than 37.5C.

Aircraft landing gear and structural components and turbo-machinery components exploited at moderate temperature (“critical components” or “components”) are subjected to severe loading, corrosion, and adverse environmental conditions and they have complex shapes varying from thin to thick sections.

Why Did We Build This?
"Prevention is better than cure" is one of the effective measures to prevent the spreading of COVID-19 and to protect mankind. Many researchers and doctors are working on medication and vaccination for corona virus. To avoid getting infected or spreading it,

I propose developing a miniature electronic device that measures temperature, chest (lung and heart) movements, and oxygen saturation. This device would be placed on the chest of the monitored person.

The monitor is to be equipped with motion sensors (3D accelerometer, 3D gyroscope and 3D magnetometer,
