This chapter discusses air breathing and liquid-propelled rocket motors. It also discusses the liquid fuel rocket motor of a fighter interceptor aircraft. At the present time, turbojets of the most diversified types are being built with thrusts of 2–6 and more tons. Motors of 4-ton thrust ...
This could be done by a liquid or gas core nuclear thermal rocket with molecular hydrogen propellant, or a solid-core nuclear thermal rocket using atomic hydrogen as propellant.) And the third, of course, was the Ares, almost dazzling in the splendour of her new aluminium paint. Gibson had...
Even though rocket motors require power, they are still referred to in the field as rocket motors. Every motor and pump in a car with an internal combustion engine gets its juice from the motors and pumps themselves. Another way of looking at it is that an engine generates power from ...
Muscle car is a term used for high-performance American coupes, typically but not confined to rear-wheel drive and equipped with a high-displacement V8 engine. In 1949, General Motors launched the first proper muscle car. The word emerged in the 1960s and early 1970s from limited versions ...
street legal, and as the name implies, you ride them off-road. With long suspensions, small (but powerful) motors, and lightweight designs, dirt bikes are their own brand of fun. Depending on where you live, it may be possible to do a lot of off-road riding by yourself or with ...
There are many types of multirotor. They are generally categorized by the number of motors used, for example a three-motored multicopter is a called a tricopter, and the configuration can also be referred to as Y3. In this post we will discuss the following types of multirotors: ...
Investigation of Second Throat Supersonic Exhaust Diffusers for the Altitude Testing of Rocket Motors Experimental and numerical investigations of a second throat supersonic exhaust diffuser (STED) system used for the simulated altitude testing of upper sta...

The end result is a very beefy rocket, so maybe add one more booster stage to it just so all that fuel can lift off the ground. Also as mentioned earlier, plasma exhaust from the target (while it's on active portion of flight) will prevent radar detection of the target. Presence of ...
Validation of an Aerothermochemical Model for Graphite Nozzle Recession and Heat-Transfer Processes An aerothermochemical model for graphite nozzle recession and heat-transfer processes in solid-propellant rocket motors has been developed. The model considers the turbulent boundary-layer flow in the nozzle...
General Motors built a diverse and differentiated product line. By 1931 GM had 31% of the market to Ford’s 28%, a lead it has never relinquished. Just to make the point that markets are never static, Toyota, a company that sold its first car designed for the US market in 1964, is...
