This is a meaningless question: coefficient of lift has nothing to do with engine power or number of propeller blades - it's a function of aerofoil type (section), dynamic pressure and reference area.
I'm not sure if I understand you question but Lift Coefficient refers to the lifting force of a wing. Engines do not provide Lift; only Thrust.
Jet-powered aircraft land on the same airports as piston-engine aircraft.
On their powered aircraft yes, they first experimented with gliders that didn't have an engine.
Dragster engine powered helicopters
the world will never know
Reciprocating (Petrol powered with pistons). Gas turbine (jet).
An aircraft that has more than 2 propellor blades per engine. Multi-blade engines usually included the capablity to vary the pitch of the propellor in order to pull more air. Multi-engine aircraft are aircraft with more than 1 engine.
fueling an aircraft powered by a piston engine it is acceptable to use a blend of 100LL and Jet A fuel The Lean Mixture rating is 100 octane
The Eurofighter Typhoon is powered by twin EJ 200 turbofans, developed by Eurojet in Munich.
If the lawnmower is not electric powered then is is probably operated by an internal combustion engine (petrol or diesel. Oddly enough, very early lawnmowers were steam powered, which means they were examples of external combustion engines.
A reciprocating airplane refers to an aircraft that is powered by a reciprocating engine, also known as a piston engine. These engines work by converting the reciprocating motion of pistons into rotary motion that drives the propeller. Reciprocating airplanes are commonly used in general aviation and smaller aircraft, offering reliability and efficiency.
