3 days ago · The transonic model helped the community better understand the physics of aircraft at cruise. The current high lift model focuses on the takeoff and landing portions of flight when the aircraft is flying slower than at cruise. Since there are more wind tunnels that can run low-speed tests, more partners can participate in the current collaboration.
The major difference is the fact that you are starting with an airplane that either is or has been flying. Restoring involves disassembly of a known quantity, inspecting and cleaning the component parts, and then reassembling the airplane. Compare that to building from a set of plans or an assembly manual.
Nov 10, 2022 · The Antonov AN-225, which was destroyed in the early stages of Russia’s invasion of Ukraine, will be rebuilt to the tune of $500 million, its manufacturer has announced.
Sep 28, 2023 · I like to install a new engine on a test stand and adjust it before bolting it onto my airplane. It is then much easier to work out the linkages, fuel line attachments, test various propellers and set the top end for maximum power using a tachometer.

Aerial refueling begins with the two aircraft closing in on each other midair. The process is dangerous and skill-intensive as the two aircraft must maintain a distance of 100 feet or less between each other. The planes must account for disruption and turbulence, especially the smaller tanker.
Once the aircraft are settled in the distance, there are currently two ways to connect the two aircraft during an aerial refueling process: “Probe-and-drogue”– This system has the tanker use a long hose with a funnel-shaped drogue to plug into a probe on the receiver. Once the tanker extends the hose, the receiver pilot must maneuver the receiving ...
Both aircraft must remain in steady flight while connected. Any sudden movements or speed changes will cause an automatic release of the filling device, requiring the connection to be remade. Once aerial fueling is complete, the tanker will power down the fueling device to disconnect the boom or drogue. The fueling devices are then retracted, and p...
If you took my advice in the engine disassembly article and noted how the parts in the engine are oriented to one another before you disassembled it, then reassembly is very simple. If not, then chances are something will be backward when you put the engine back together. Take a close look at the connecting rod.
Model airplanes powered by two-stroke or four-stroke glow engines have a long history in our RC hobby. Chances are, when you first started flying that you were introduced to the hobby with an electric-powered airplane.
