What are reciprocating engines for aircraft called heat engines?

Your question isn't clear. Are you asking WHY reciprocating engines for aircraft are called heat engines, or are you asking whether or not they are considered heat engines? Or are you asking something else entirely? Heat engines include many types of engines, and probably all of them. The term simply describes any type of engine that uses heat to generate power.
Reciprocating engines for aircraft are simply piston-driven (reciprocating) internal combustion engines. They usually burn higher octane low-lead gasoline. The higher octane helps the engines burn fuel more efficiently, which helps high up in the air where the varying oxygen content and turbulence may diminish the less-efficient lower-octane fuels.
Not all aircraft use reciprocating engines. Some other aircraft engine types are jet engines and turbo-prop engines. Both of these run on jet fuel. They differ in that jet engines completely eliminate props (propellers) and work by creating thrust from pressurized burning fuel. Turbo props are a sort of hybrid, where jet fuel powers the props, which in turn create movement in the same way that reciprocating engines do.

Heat engines use heat to do work?
Yes. Heat engines come in various forms. For example, internal combustion using gasoline or diesel, external combustion (not much used), steam engines reciprocating or turbine, gas turbines, rocket engines.
How do you heat and cool airplanes?
Modern aircraft are heated and cooled inside by 'bypass airflow' from the engines.
What is the function of a piston ring?
The three main functions of piston rings in reciprocating engines are:Sealing the combustion/expansion chamber.Supporting heat transfer from the piston to the cylinder wall.Regulating engine oil consumption.
The advantage and disadvantage of gas turbine?
Advantages of gas turbine enginesVery high power-to-weight ratio, compared to reciprocating engines;Smaller than most reciprocating engines of the same power rating.Moves in one direction only, with far less vibration than a reciprocating engine.Fewer moving parts than reciprocating engines.Low operating pressures.High operation speeds.Low lubricating oil cost and consumption.Disadvantages of gas turbine enginesCost is much greater than for a similar-sized reciprocating engine since the materials must be stronger and more heat resistant. Machining operations are also more complex;Usually less efficient than reciprocating engines, especially at idle.Delayed response to changes in power settings.These disadvantages explain why road vehicles, which are smaller, cheaper and follow a less regular pattern of use than tanks, helicopters, large boats and so on, do not use gas turbine engines, regardless of the size and power advantages imminently available.
Machine that transforms heat into mechanical energy?
A ficticious heat engine that works at the maximum theoretical efficiency is called a Carnot engine. Real engines, that obviously work at a lesser efficiency, include the combustion engines found in cars.A ficticious heat engine that works at the maximum theoretical efficiency is called a Carnot engine.

Why were flights cancelled with the eyjafjallajokull volcano?
The 2010 eruption of Eyjafjallajökull produced a large ash cloud, which is dangerous to aircraft. It can damage aircraft windshields and engines, especially jet engines. Ash that enters a jet engine melts in the intense heat and resolidifies within the engine as glass, which can cause a stall.
Why do engines get discolored?
engines get discolored because of the heat . the heat comes from combustion from gass and air
Does heat engines use heat to do work?
by engine
Does car works on heat produced by petrol when it is burnt?
Yes. Gasoline and diesel engines are both heat engines.
Is a engine in a car the same as a heat engine?
A car engine is a heat engine, but there are various types of heat engines outside the realm of car and truck engines.
How are heat engines classified?
heat engines are classified on the location of the combustion chamber , if it is outside the whole set up then it is external heat engine and vice versa.
Are gasoline and Diesel engines heat engines?
Yes, gasoline and diesel engines are heat engines. The energy released by the burning fuel causes the gas in the cylinders to expand and push the pistons, which in turn do work.
