Upside down or right side . at 20" below or 1000 above Without electricity, no modern bombercouldeverleavetheground. Electricity starts the motors, retracts the landing gear, changes the propeller pitch, works the wing flaps, opens the bomb doors, powers the radio and inter-communication sys tem, operates the instruments, gives light for the crew to work by. No ordinary electrical appa ratus can handle these jobs in a bomber. The whole complicated sys tem must work as well upside down as right side up. It must function in a tropical thunder storm and in 200 below zero altitudes. And it must be de signed to save every precious fraction of an ounce and inch. Developing electrical equip ment for bombers-and pro ducing that equipment in quan tity-is a job made to order for Westinghouse "know how." Here are some of the West inghouse products that are go ing into American bombers today: * Instruments designed so one instrument does the work of two. * Radio equipment and special blind-flying devices. * Electric motors that develop more horsepower per pound than any other motors ever built. * Instrument lights that cast invisible rays on dial markings. * Electric generators which weigh only 42 pounds, yet pro duce as much electricity as 35 standard automobile genera tors weighing 23 pounds each. In makingthesethings, the long range work of Westinghouse Research and Engineering Lab oratories has played a signifi cant part. Discoveries in many fields-in electronics, physics, chemistry, mechanical and elec trical engineering-are now bearing fruit in the production of better and more powerful weapons of war. Many of these discoveries, we believe, will someday help to make a better peacetime world. * * * This advertisement has been re viewed by Government authori ties, and contains no Information of military value to the enemy. @ Westinghouse PLANTS IN 25 CITIES-OFFICES EVERYWHERE WESTINGHOUSE ELECTRIC & MANUFACTURING COMPANY, PITTSBURGH, PA.
