Ağır araç için “kinetik enerji geri kazanım sistemi”ni ve 3 rotorun düşük/ yüksek tork modlarını, küçük sayısal bir örnekle birlikte tek bir teknik parça halinde yerleştiriyorum.
Kinetic Energy Recovery Subsystem with Three Rotors (Illustrative)
Concept:
A heavy machine (e.g. grader, tank or large truck) is equipped with a kinetic energy recovery subsystem consisting of three low‑torque dynamo/flywheel rings mounted around a drive shaft. The system operates in two main modes: low‑torque continuous harvesting and high‑torque boost harvesting.[1][2]
Operating Modes
- Normal driving / light work (Low‑torque harvesting)
- Each rotor is lightly coupled to the shaft via a controlled electromagnetic or friction interface.
- The additional torque seen by the shaft is kept just above the threshold of perceptibility for the operator.
- Example design target: total generator mechanical load of about 10 kW at cruise.
- This mode is used during normal road driving or light operation, aiming to recover energy without noticeably increasing fuel consumption.[3][4]
- Heavy work (High‑torque boost harvesting)
- When the machine performs heavy-duty tasks (continuous grading, heavy lifting, armoured manoeuvres), the control system allows higher generator torque.
- The three rotors together can temporarily draw up to 30 kW of mechanical power from the shaft (approximately three times the normal harvesting level).
- This harvested power is directed to the energy storage system (batteries or super‑capacitors) to support hydraulic systems, traction motors or auxiliary loads during peak demand.[2][5]
Numerical Illustration (Conceptual)
Assume:
- Three rotors on a single shaft.
- Low‑torque mode: total mechanical power into the kinetic subsystem $$ P_{\text{low}} \approx 10 \,\text{kW} $$.
- High‑torque mode: total mechanical power $$ P_{\text{high}} \approx 30 \,\text{kW} $$.
If the machine remains in:
- low‑torque mode for 1 hour:
- mechanical energy into the system $$ E_{\text{low}} \approx 10\,\text{kW} \times 1\,\text{h} = 10 \,\text{kWh} $$.
- high‑torque mode for 0.5 hours during intensive work:
- $$ E_{\text{high}} \approx 30\,\text{kW} \times 0.5\,\text{h} = 15 \,\text{kWh} $$.
Total mechanical energy harvested in that period:
- $$ E_{\text{total}} \approx 25 \,\text{kWh} $$.
With an overall conversion and storage efficiency of, say, $$ \eta \approx 0.8 $$:
- net electrical energy stored
$$ E_{\text{elec}} \approx 0.8 \times 25 \,\text{kWh} \approx 20 \,\text{kWh} $$.
This electrical energy can then:
- power electric drive or hydraulic assist during later manoeuvres,
- or cover auxiliary loads so that the diesel engine can run at a more efficient operating point, improving overall fuel economy.[1][2][4]
Note: The “three times” statement here means three times the harvesting power during boost mode compared to the normal mode, not three times more energy than the engine supplies. All energy ultimately originates from fuel, braking events or gravitational potential; the subsystem’s role is to recover and reuse it, not to create energy from nothing.[6][7]
Bu bölüm, hem senin “hissedilir en az tork + gerektiğinde 3 kat enerji çekme” fikrini, hem de kinetik enerji geri kazanım sistemi (KERS) literatürünü bozmadan anlatıyor.[1][5]
İstersen benzer mantığı şimdi uzay aracı white paper’ında “Low‑Torque Kinetic Harvesting Rings” diye bir alt başlık olarak da uyarlayayım mı?
