In 1969. El Salvador and Honduras in the Football War.
El Salvador had P51 Mustangs and Honduras flew F4U Corsairs.
The above was the last instances of fighter piston aircraft seeing combat. Most militaries continue to this day to use piston engine aircraft for certain specialist duties: transport, forward fire control, observation, COIN, and other light duties. However, even here, most are slowly being phased out in favor of the turboprop.

Why was the jet inveted?
The jet engine? 1. There are theoretical limits to the speed of propellor-driven aircraft. 2. There are practical limits to the power of propellor propulsion. 3. Piston engines, for given output, are large, and need cooling. The jet engine can propel aircraft at supersonic speeds, can be scaled up to very large powers, especially by using fan/ bypass technology, and the jet turbine can be made self-cooling by the large volumes of air it consumes. One example of a jet turbine's superiority over piston engines is the Chinook helicopter, which uses two turboshaft (jet engine with a shaft connection) to drive its large rotors. This design is superior to using piston engines.
How do aircraft engine manufacturers do it?
Aircraft engine manufacturers build and repair aircraft engines using automated robots and other computer-aided equipment.
Which engine is best for an aircraft?
It totally depends on what you are using the aircraft for. Sometimes you need power over fuel efficiency, sometimes you need fuel efficiency over power. It is dependent on the situation where the engine will be used. Some engine examples; Piston props (radial and v engine), internal combustion props, turboprops, turbofans, axial turbojets, centrifugal turbojets, ramjets and scramjets.
What is the advantage of using composite material?
jet engine problems using composite materials for aircraft
What engine operates using a three-sided metal rotor instead of the traditional piston-and-cylinder arrangement?
Rotary or Wankel engine.
What does a turboprop do?
Answer:The combination of the words turbine and propeller in techno jargon will give you the word "turboprop". A turboprop engine is a turbojet (gas turbine) engine, which powers the propeller/s. A conventional jet engine produces its thrust in large part due to the heated gasses escaping out the rear of the engine. While this is very useful for aircraft which fly at high speeds and high altitudes, it is less desirable for aircraft which are designed to fly at slower speeds and take off from smaller runways.A turboprop engine is a jet engine which converts the bulk of its thrust into rotational energy for powering a propeller. This allows jet engines, which are a high-rpm low-torque engine to be used in situations where low-rpm and high-torque are needed instead.The higher reliability and efficiency of a jet or turboprop engine as compared to an internal combustion engine makes them very desirable for aircraft designs which, in the past, would have utilized internal combustion engines.Answer 2A turboprop is a jet engine with a propellor attached - a jet engine is a turbine (fan) that compresses a large volume of air for combustion in a chamber as a opposed to a piston - a turbo charger on steroids - the propellor is attached to the central shaft of the fan blades - the two exhaust tubes on either side of the front of the turboprop are for the jet exhaust and it actually can add to the speed of the aircraft - the jet engine is usually backwards on a turboprop, the air intake under the engine is sent to the back which is really the front of the jet turbine, compressed by the fan blades (which drive the propellor) then sent to the combustion chamber where it is mixed with fuel and ignited - then exits through the exhaust tubes which bend to point backwards adding to the total thrust of the engine Often the word turboprop is confused with turbo charged which is a regular piston engine that uses a turbo charger (air compressor) - the P-38 lightning twin boom fighter of WW2 is a great example of a turbocharged engine and once you hear the sound the turbo chargers make you never forget itTurbo prop engines address a need for a compromise between propellor and jet engines - propellors are efficient at slow speeds to about 350 mph (meaning the amount of fuel used for speed and range) and dont have as much power as a jet - jets are effecient from about 300mph up and are more powerful than a piston engine but use more fuel - a turbo prop has nearly the power of a jet without as much fuel use and fills the gap for a mid range speed of about 200 to 400 mph - rarely see turboprops on low speed aircraft because of the extra fuel use with exception of some STOL bush style aircraft like the cessna caravan and the new quest kodiak that need the extra power for short/rough field useAlso turbo props can reverse thrust like a jet engine but do so usually by changing the angle of the propellor blades - another big advantage over piston engines for short runways - also turboprops use jet fuel since they are jet engines so they are being used more frequently in countries outside USA where avgas is becoming hard to find (not much general aviation aircraft but lots of jet airliners in many countries)A big advantage to using turboprops is how long they can be flown before a complete overhaul - the time can vary a lot by engine but an average time for a piston engine is about 1800 to 2000 hours and a turbo prop about 3000 to 3600 hours - so you can fly a turboprop a whole lot longer between major overhauls.
The engine of an airplane does what?
The engine of an aircraft gives the aircraft power to create lift, either using wings (in the case of an airplane) or rotors (in the case of an helicopter) or both (in the case of an autogyro).
A plane without an engine?
A glider which is alight aircraft designed to fly for long periods without using an engine.
Who is the inventor of an aircraft engine using plain alcohol as fuel?
EMBRAER of BRAZIL, has an aircraft flying on Ethanol, It is called IPANEMA and it is a cropduster.
How airplanes work?
Fixed wing aircraft work by using a kind of propeller or engine to pull the aircraft forward and the wings produce lift.
What might an aircraft designer today think of the idea of using a steam engine to power an airplane?
Steam engines are too heavy to power aircraft.
What is an engine called where the fuel is burned in a duct using cmpressed air by the forward speed of an aircraft?
ramjet
