Looks like, by lifting, it means maintaining the 1 kg mass at a certain height from the testing device.Need to know how long it took to displace ball 24mm. But 1KW is a lot of power for lifting 1Kg a measly 24mm.
So no work is actually done on the 1 kg mass in this case.
But that is not my point. I was more interested in the engine output power.
You can get an idea of what I mean if you compare this to the output power in KW of a helicopter engine and the kind of weight it needs to lift.
Specifications & Dimensions
|Helicopter||R44 Police Helicopter|
|Engine||Lycoming IO-540, six cylinder, fuel injected|
|Horsepower||Derated to 245 hp for takeoff and 205 hp continuous|
|Maximum Gross Weight||2500 lb (1134 kg)|
|Approximate Empty Weight (including oil, standard avionics, and standard police package)||1638 lb (743 kg)|
245 hp = 183 KW
So, 183 kw / 1134 kg = 0.16 kw/kg = 160 watt per kg (which is way lower than 1000 watt / kg)
