The first stage has a very important three-minute job—blast the second stage and the attached payload up to an altitude of about 100km before peacing out and falling into the ocean.4 The first stage, like almost all parts of Falcon 9, is manufactured in SpaceX’s California headquarters...
Extended Range Operation: The distance from the alternate airport is higher than the aircraft's standard at the static atmosphere at least one point to any extended range operation on the planned flight path of the aircraft. The approved cruise speed is not valid when the engine is not working...
MegaSquirt uses all these factors to determine the fuel pulse width - longer pulse widths mean more fuel (richer), shorter pulse widths mean less fuel (leaner). To understand these, we will start with the basics: the Ideal Gas Law, the REQ_FUEL value, and the fueling equation....
With numerous trains, boats, trams, cable cars, and funiculars to choose from, the best way to make the most of solo female travel in Switzerland is to buy aSwiss Travel Passor a series ofDay Passes, depending on how long you wish to spend at each location and what your budget is. Y...
Here's how to find the right travel insurance plan for you and your next adventure. What travel insurance covers Depending on the type of coverage you’re looking for, the chart below will help you determine ...
Ramjets are efficient at high speeds but require other propulsion systems for takeoff and acceleration, due to their inability to produce thrust at low speeds. As anyone who's ever belly flopped off a high dive can tell you, when you hit a fluid without giving it time to get out of the...
Additionally, the hydrogen content of the jet fuel and syn-jet fuel (i.e., 13.7% and 15.3%, respectively) is used to determine the water vapor emission factor based on the stoichiometric condition that 1 mol of H2produces 1 mol of H2O upon combustion. This yields 1.23 kg and 1....
short for electric vertical take-off and landing. Uber's design has four sets of twin rotors that it uses for vertical lift and a single rotor for forward propulsion. It would cruise at speeds of 150 to 200 miles per hour at an altitude of 1,000 to 2,000 feet and could travel 60 ...
I hope that a full chemical and spectral analysis will be done to determine without doubt that these naturally occurring radionuclides are native to this beach and not introduced. Part of my cautious approach to this is the public knowledge that radioactive materials were dumped at theFarallon Isl...
Pitot tubes, named for physicist Henri Pitot, are designed to measure air-pressure differences to determine the velocity of the air. Data about the air flow is sent to the sequencer, which then selects from the three modes of ejections: Mode 1: low altitude, low speed - Mode 1 is for...
