How does rudder braking work?

In addition to the answers and comments that clarify the potential confusion between 'normal' rudder controls and wheel braking with rudder toe-brakes, I thought it might be interesting to add that at ...

F15 Startup Intake drop

when the intake takes in supersonic air the engine may experience turbulence and hence get damaged. Hence, the inlets are responsible for turning the supersonic air into subsonic such that the engine ...

What different intake designs are there, and what are their pros and cons?

It is mostly a tradeoff between complexity and speed. High speed inlets not only fundamentally need to be more complex for efficient operation (more oblique shocks required before the normal shock), ...

How does rudder braking work?

I've always heard "rudder brakes" called toe brakes, but I think I understand what you mean. When you're operating the brakes, you're rotating the pedals about their centers using your ...

What are those little pieces for on the C27J?

Those are vortex generators. In this case they are to mitigate bad handling if it loses the “worst case” (critical) engine: Seventeen vortex generators were added to the left-hand side of the ...

Do Blended Wing Bodies produce more induced drag compared to a conventional tube and wing design? Does this affect its performance?

They don't produce additional lift. Aircraft produce lift equal to weight. The added lift of a fuselage may reduce the angle of attack required by the wing to achieve lift equal to weight -- but for ...

Can smaller wing area improve the aircraft experience during turbulence?

A better example would be the B-1. It began as a supersonic, high-flying bomber (B-1A) but was soon converted to a subsonic, terrain-following intruder (B-1B) with limited stealthing to increase ...

Can smaller wing area improve the aircraft experience during turbulence?

Gust analysis is a quite complex matter, so complex that big airplane companies have dedicated departments only for this topic. Anyway an easy way to understand how a gust influences the flight ...

Can smaller wing area improve the aircraft experience during turbulence?

The F-14 with highly swept wings is less affected by air loads like turbulence than at low sweep, as shown by maximum allowed airspeed. Max speeds (TMN is true mach number) are higher when wing sweep ...

Can smaller wing area improve the aircraft experience during turbulence?

Excellent question presentation, because this one was originally designed in a similar manner as the F-14. Not only faster, but higher, in the Stratosphere, where turbulence is less common. The effect ...

How do I choose Cl during cruise flight with a given MTOM and variable S?

You might find Lee Nicolai's white paper "Estimating R/C Model Aerodynamics and Performance" a useful guide and reference. Look under "series resources/design event resources" at ...

Why aren't there any larger autogyros/gyrocopters?

Simple supply and demand. There just aren't that many people interested in large autogiros to justify the costs of producing and supporting a certified aircraft.

Why aren’t there Seaplane AWACS?

Seaplanes need extensive support infrastructure, and are hard to operate in all but the smoothest of sea states. They're also hell to maintain because of the salt water corrosion affecting everything (...

Why aren’t there Seaplane AWACS?

There is also a political element to this question. If a nation has no political desire to use force away from their own territory, they can simply use land based aircraft operating from their own ...

Why aren’t there Seaplane AWACS?

Because we are no longer in the age of battleships. In the age of battleships, your major firepower came directly from ships (big guns), and those ships would have benefited greatly from AWACS or ...

Why aren’t there Seaplane AWACS?

Most of the current AWACS models are either based on civilian aircraft (E-3, E-7), or have been adapted to other roles (E-2 -> C-2). The obvious advantages of this is that any R&D costs are ...

Why aren’t there Seaplane AWACS?

The E-2 Hawkeye is a carrier based aircraft that fills that role for the US Navy. It is an older airframe, but very capable, and a replacement is in work. https://en.wikipedia.org/wiki/...

Why aren't there any larger autogyros/gyrocopters?

Why aren't there any larger autogiros? Because you would basically have a machine with the same limitations of a helicopter (in terms of speed and maintenance) but, since the rotor of an autogyro ...
