How much horsepower can a radial engine generate?

How much horsepower can a radial engine generate?

They can produce a lot of power. A typical radial engine in a B-17 has nine cylinders, displaces 1,800 cubic inches (29.5 liters) and produces 1,200 horsepower. Radial engines have a relatively low maximum rpm (rotations per minute) rate, so they can often drive propellers without any sort of reduction gearing.

Do they still make radial aircraft engines?

Modern radials

A number of companies continue to build radials today. Vedeneyev produces the M-14P radial of 360–450 hp (270–340 kW) as used on Yakovlev and Sukhoi aerobatic aircraft.

Which motor is best for RC plane?

For your first plane I recommend a motor kv between 850kv and 1500kv. The next factor to considering a motor is size. Many beginners will end up significantly over-powering their planes and doing so adds momentum in crashes. Lighter, slower planes do not break as often as fast, heavy planes.

What engines do RC planes use?

The most popular types for radio-controlled aircraft are internal combustion engines, electric motors, jet engines, and rocket engines. Three types of internal combustion engines are available being small 2 and 4 stroke engines.

Why don’t we use radial engines in cars?

Radial Engines
This is useful in airplanes because you can put a bunch of cylinders right at the nose of a plane and the air cools them all equally. In cars, it’s less useful, though, because it’s a big lump of engine to design around.

Do radial engines burn oil?

This is especially true of radial engines, which have some cylinders inverted, letting oil pool on the pistons when not running, leaking past and getting into the combustion chambers. That’s why radial engines tend to expel huge clouds of smoke when started, as that oil burns off.

How much do radial engines cost?

What size motor do I need for my RC plane?

Electric motor power is stated in watts. 750 watts = 1 horsepower. An easy way to estimate power needs for RC hobby applications is to use 100 watts per pound for sport flying, 150 for aggressive aerobatics, 200 watts per pound for 3D flying.

How much thrust does an RC plane need?

To calculate this with the weight of your model plane, simply replace the 1 by the weight and multiply the number on the left side by the weight, so if your model plane is 1.2 Kg and it is a trainer type model plane, we are going to use 0.7 : 1 = 0.7: 1.2 by multiplying this we obtain 0.84 Kg (840g) this is the thrust …

How high can RC planes fly?

34,800 ft
The highest altitude remote-controlled (RC) model aircraft flight is 10,607 m (34,800 ft), and was achieved by Paul Kaup, Jake Minker, Nick Ross, Eric Gordon, Rachel Stark, and Dani Deckert (all USA) in Truth or Consequences, New Mexico, USA, on 13 October 2019.

How far can you fly an RC plane?

So how far can an RC plane fly? In ideal conditions, you can get a distance of 1.5km with an RC plane that operates at 2.4Ghz, or several kilometers using the UHF (Ultra High Frequency). Other factors include the sensitivity of the receiver, positioning of the antenna, and the environment in which you are flying.

Are radial engines fuel efficient?

According the REI, conventional internal combustion engines convert only about 30 percent of fuel into usable energy, with the remaining energy lost to friction, heat, and incomplete combustion. The RA-92’s radial design allows it be up to 20 percent more fuel efficient, so it creates power with less fuel.

Why do radial engines smoke on start up?

The big clouds of smoke that are coughed out when a big aircraft radial is started result from the fact that such engines have several cylinders that point downward. On shut-down, oil drains from above and, despite each cylinder having an inward-projecting “spigot,” some of this oil goes into the lower cylinders.

Why radial engines are preferred?

Reliability – Simply put, the radial engine is generally much more reliable. This is because it features a shorter crankshaft, simpler design, and creates less vibration. That less vibration means that it will suffer from greatly reduced levels of wear and tear during use.

Are radial engines reliable?

A radial engine is generally more reliable. This is because it includes a shorter crankshaft and therefore exhibits less vibration, meaning greatly reduced levels of wear and tear during use.

What does KV mean for RC motors?

Kv describes the RPM (revolutions per minute) a motor does per Volt that is put into it. Generally speaking the more Kv a motor has, the more RPM and more power. For example, a 9000Kv motor would be faster than a 2200Kv motor.

How much thrust does it take to lift a pound?

A “pound of thrust” is equal to a force able to accelerate 1 pound of material 32 feet per second per second (32 feet per second per second happens to be equivalent to the acceleration provided by gravity).

Do I need a Licence to fly a RC plane?

You don’t need a licence to fly an RC plane recreationally in the US at the moment. But, depending on what country you live in, you may need to take an online test, and mark up your model so that it can be identified.

Can I fly my RC plane anywhere?

The FAA stipulates where RC models can be flown for fun based on whether the location is in controlled or uncontrolled airspace. UNCONTROLLED AIRSPACE is where there are no air traffic controllers directing the air traffic.

Do you need a Licence to fly RC planes?

Is it legal to fly RC airplanes?

UNCONTROLLED AIRSPACE is where there are no air traffic controllers directing the air traffic. If you’re an FAA-registered recreational RC pilot or your model aircraft doesn’t require registration, you can fly in these areas without additional FAA permission. You must keep your aircraft at altitudes below 400 feet.

What does Blue smoke mean aviation?

Blue smoke
This means there’s a contaminant within the cylinders and it’s combusted along with the air and fuel. This cross-contamination is caused by engine wear to the cylinders, pistons and valves, along with failed seals like the piston rings.

How do we prevent hydraulic lock?

To avoid hydraulic lock during engine start, the propeller should be turned through a few revolutions by hand in the direction of rotation (with the ignition switches off).

How reliable are radial aircraft engines?

Why radial engine is the best?
