10. Do you think turning to nature for engineering ideas is a good approach? Explain. ge: The 9. If you were on a design team, how would you further explore or develop bird-inspired features to enhance aircraft efficiency and safety? 9. If you were on a design team, how would you further explore or develop bird-inspired features to enhance aircraft efficiency and safety? 10.Do you think turning to nature for engineering ideas is a good approach? Explain. 7. Do you think this technology could be quickly adopted in commercial aviation, or would it be more suitable initially for smaller aircraft? Why? 8. What are potential concerns or trade-offs engineers might face when incorporating multiple rows of flaps onto airplane wings? how do these birdlike flaps compare to traditional plane flaps and spoilers in term of contral and automation. 6. How do these birdlike flaps compare to traditional plane flaps and spoilers in terms of control and automation? 7. Do you think this technology could be quickly adopted in commercial aviation, or would it be more suitable initially for smaller aircraft? Why? 4. How might these bird-inspired flaps help reduce the risk of stalls during challenging flight conditions? 5. What specific aerodynamic benefits do the front rows of flaps provide in terms of airflow management? 6. How do these birdlike flaps compare to traditional plane flaps and spoilers 3. By approximately how much did adding five rows of bird-inspired flaps improve lift in the wind tunnel experiments? 4. How might these bird-inspired flaps help reduce the risk of stalls during challenging flight conditions? 4. How might these bird-inspired flaps help reduce the risk of stalls during challenging flight conditions? 5. What specific aerodynamic benefits do the front rows of flaps provide in terms of airflow management? 6. How do these birdlike flaps compare to traditional plane flaps and spoilers in terms of control and automation? 39.1 - Una portata \( \dot{m}=0,04 \mathrm{~kg} / \mathrm{s} \) di R134a descrive un ciclo frigorigeno ideale (Figura 39.4). La temperatura del refrigerante nel- l'evaporatore è \( T_{1}=-20^{\circ} \mathrm{C} \), mentre quella del condensatore è \( T_{3}=+40^{\circ} \mathrm{C} \). Determina- re il coefficiente di prestazione del ciclo fri- gorigeno \( C O P_{\mathrm{F}} \), la portata in volume \( \dot{V}_{1} \) che deve trattare il compressore e la potenza ideale \( P_{\text {id }} \) assorbita dal compressore. \( C O P_{\mathrm{F}}=3,1 ; \dot{V}_{1}=0,0059 \mathrm{~m}^{3} / \mathrm{s} ; P_{\text {id }}=1,68 \mathrm{~kW} \)
