Great comparison of both the regular J-20 with WS-10C engines and the new J-20A with WS-15.

The protruding hump behind the cockpit reduces drag.Aestethically the J-20A looks more well proportioned now due to the protruding hump behind the cockpit.
Does it mean the WS10C has higher dry power? The WS-10 above is using afterburner.Great comparison of both the regular J-20 with WS-10C engines and the new J-20A with WS-15.

You mean "low dry power"?Does it mean the WS10C has higher dry power? The WS-10 above is using afterburner.
obviously ws-10c should have higher dry power compared with ws-10You mean "low dry power"?
Got it.obviously ws-10c should have higher dry power compared with ws-10

Not necessarily indicative of a lack of power. There are many reasons why jet fighters take off using after-burnerMy bad. You are right.
@Deino Does it mean the WS15 has higher dry power? The WS10C above is using afterburner.
I'll try to illustrate the engine with some simple descriptions. (chemical energy engine)Not necessarily indicative of a lack of power. There are many reasons why jet fighters take off using after-burner
Jet fighters often use afterburners during takeoff to achieve the necessary thrust for rapid acceleration and lift-off, especially when operating from shorter runways or aircraft carriers. Here are a few key reasons why afterburners are used:
While afterburners provide a powerful thrust boost, they are also fuel-intensive and are typically used sparingly to conserve fuel for the mission ahead.
- Increased Thrust: Afterburners inject additional fuel into the jet engine’s exhaust stream, igniting it to produce a significant boost in thrust. This extra power is crucial for quickly reaching the speeds needed for takeoff1.
- Short Runways: On aircraft carriers or short runways, the available distance for takeoff is limited. The additional thrust from afterburners helps jets achieve the required speed in a shorter distance2.
- Heavy Loads: Fighter jets often carry heavy payloads, including weapons and fuel. The extra thrust from afterburners helps lift these heavier loads off the ground more efficiently1.
- Quick Response: In combat situations, the ability to take off quickly can be critical. Afterburners allow jets to accelerate rapidly, reducing the time needed to get airborne and into action2.
Is there a specific jet or scenario you’re curious about?
