First let's clear up some things: A SCRAM jet is a Supersonic Combustion RAm Jet, where the flow speed in the combustion area is still supersonic. … Using it in combination with a Ram jet would result in separated, subsonic flow with little pressure recovery in the combustion area, and very little thrust could be produced. …

I am sure every airline has such a model, which will include actual wind and temperature information, but it will contain proprietary data which is not publicly available, unless you have a proven int …

If you can live with that, a subsonic wooden jet is easy to design. … In fact, there was already a wooden jet fighter. The Horten IX (or Gotha 229) had wooden wings and a steel tubing frame in the mid wing with wooden skin. …

Actually, there are three types of trails an aircraft can leave in the sky: 1. Condensation of water vapor in the exhaust gas and/or the wake This needs the very cold, very dry air at higher altitud …

Only aerodynamics? Then the answer is simple: It lacks artificial stability. In a paper by Ray Whitford on fighter design he published a comparison study between the conventional Jaguar and an advanc …

The worst case depends on the kind of bullet. If a tracer bullet hits an empty fuel tank which contains a mixture of air and fuel vapor, an explosion will follow. A regular bullet will just punch a ho …

They could only be engaged with success when they were flying in for a landing with empty tanks or by chance, when the jet pilot was unaware of his opponent. …

The flow enters the compressor at approximately Mach 0.4 to 0.6 in order to ensure a high mass flow with still subsonic compressor blade speeds. Compressing the air allows to reduce flow speed, and be …

The air is compressed in the compressor section of the engine and heats up. Hot air is able to hold disproportionally more water in gaseous form than cold air, so all that water will vaporize and ente …

Here, the fuselage-mounted landing gear can be made short and light (which is how the Do-328 JET evolved). Still, both versions exist. … And the ones where the engineers did not know how to attach a jet close to the wing*. Aerodynamically a mid-wing position would be best. …

Long range missiles benefit from the lower air density at higher altitudes. Short-range missiles normally fly line-of-sight to the target, but for distances of more than 8 or 10 km, the range of the m …

They are fixed, and many attempts were made over the years to have an aiming capability - and all failed. That should tell you something. The earliest aereal combats used indeed handguns which were po …

As an addition to @xxavier's excellent answer: RC planes have far lower wing loadings, so the pressure difference between ambient and over wing pressure in case of model airplanes is far too small to …

to contemporary propaganda which claimed that it had been developed in only three months, Heinkel had been working on this configuration for almost a year when the proposal for a cheap, single-engine jet …

No. You need to know one more parameter: How much fuel will be consumed per unit of time. In the end, thrust is created from heating some of the air entering that engine, and only if you know what pr …
