How about that airplane, that crashed in Brazil, from a stall. That had to be a terrifying last couple of minutes. Prayers to all.

The P-47 Thunderbolt and the P-51 Mustang were both designed and built for different purposes, but they both achieved great success in combat. The P-47 was a heavy fighter-bomber that could carry a large payload of bombs and rockets, while the P-51 was a long-range escort fighter that could protect the bombers from enemy fighters. Both planes had their advantages and disadvantages.

The answer is not so simple but in general, the P-51 was faster than the P-47 at low and medium altitudes, while the P-47 was faster than the P-51 at high altitudes. The reason for this is mainly due to the different engines and turbochargers that each plane used. The P-51 used a Packard V-1650 Merlin engine, which was a liquid-cooled V12 engine that produced 1,720 horsepower. The P-47 used a Pratt & Whitney R-2800 Double Wasp engine, which was an air-cooled radial engine that produced 2,500 horsepower. The Merlin engine had a better power-to-weight ratio and was more efficient than the Double Wasp engine, which gave the P-51 an edge at lower altitudes.

The Double Wasp engine had a huge turbocharger that boosted its performance at higher altitudes. A turbocharger is a device that compresses the air entering the engine, increasing its density and oxygen content. This allows the engine to burn more fuel and produce more power. The turbocharger of the P-47 was located behind the cockpit and connected to the engine by a long duct. The duct had an intercooler that cooled down the compressed air before it reached the engine.

The turbocharger of the P-47 was very effective at high altitudes, where the air pressure and temperature were lower. It could maintain a constant manifold pressure of 52 inches of mercury up to 30,000 feet, while the Merlin engine could only reach 42 inches of mercury at 25,000 feet. This gave the P-47 a significant advantage in speed and climb rate at high altitudes, where it could reach over 700 km/h.

The aerodynamics of each plane also played a role in their speed performance. The P-51 had a sleek and streamlined design that reduced drag and increased lift. It also had laminar flow wings that smoothed out the airflow over the wing surface, further reducing drag. The P-47 had a bulky and rugged design that increased drag and weight. It also had conventional wings that created more turbulence and drag. The aerodynamics of the P-51 gave it an edge in maneuverability and agility over the P-47.

So, to sum up, the P-51 was faster than the P-47 at low and medium altitudes because of its lighter weight, more efficient engine, and better aerodynamics. The P-47 was faster than the P-51 at high altitudes because of its powerful turbocharger and larger engine. Both planes were excellent fighters that served their roles well in World War II.

Most have seen the pic of the A-10 and how it was built around it's Gatling gun. Well the 47 seems to have been built around that complex turbo-supercharger setup:

Big days yesterday and today, lots of work.... got one of the dope repair wings finish painted and some prep for the new wing build tables.... 16' long. Today welding the pallet rack ends to their new configuration the tables will be 32" tall. It will enable cradle fixtures to hold wing skins for an accurate, true build. We pulled the stallion out of the trailer and set it all back on its gear, it'll be much easier to move about the shop this way.
The stallion is a unicorn plane for me... in the parlance of gone in 60 seconds, it's my Eleanor. An amazing airframe designed and engineered by Martin Hollman.... he did extensive FEA when he created it in the 90's.
He was the engineer behind the Lance Neibauer series of aircraft during the 80' and 90's, the series everyone knows as the lancair. This particular bird shares a wing with the lancair es. As built with the original continental engine it's a solid 200 to 220 kt airplane at 14000'. Our goal is to put a tio540 on it... that should get us to 17k ft and solid 250mph ground speeds. The guys in the back seat are a couple good friends, that's the furthest rear seat ( it seats six) it actually has more space side to side than a 170..... and that's the back seat. Martin was 6'6" it's even wider across the front seats.lots of head space. It has a massive useful load with a full wet wing... if you want it, 180 gallons. It'll fly 2500 miles non stop. Way longer leggs than my bladder. I plan to build a sit down liquid relief station into the aft seat with a tube out the tail. It's not a jet but it's going to be the most efficient means of fast cross country travel I can figure to fit my needs.

Wow. Seeing the inner workings of that complex experimental makes my RV-7 project look like it came from the Children's toy section.

[rsrguy]

Hahahaa.... that is hilarious. The bottom line here is that even rv builders do an amazing job at making their airframes complex.

Close air support.

Watched dad do that close up every summer growing up...

Military guys might appreciate watching a 2 hour documentary on the F14 Tomcat...history, evolution, pilot interviews, etc.

I had a few friends who were pilots there, sadly they are no longer with us.
