A man signals as the aircraft taxis and takes off from the airfield. The aircraft in flight over a sea. The aircraft releases torpedo in water. (World War II period).
A man explains graphical presentation of the proper speed and altitude combination for torpedo release in United States.
New techniques in aerial torpedo attack, United States. A man explains the graphical presentation of the proper speed and altitude combination for torpedo release. An aircraft in flight releases torpedo in water. The torpedo moves in water. The torpedo launching guide. In double entry type graph, the combination of 2 coordinates gives the third coordinate. Dropping speed and dropping altitude data is entered in the chart. It gives the entrance angle. The man explains the concept of point of release to the point of hitting target using the graph. The cross wind effect on torpedo drop is explained. Time column on graph gives time of fall of torpedo. Release of torpedo with proper range is necessary. Radar ranging requires teamwork between the pilot and the radio man. Demerits of long and short range is explained. (World War II period).
Diagrammatic presentation of full range of entrance angle for shallow and deep water for release of torpedo,in United States.
New Techniques in aerial torpedo attack, United States. A diagrammatic presentation shows the full range of entrance angle. The range for shallow water is18 to 22° and for open sea or deep water is 22 to 32°. Extreme angle to be avoided. A Grumman TBF aircraft in flight. The aircraft releases torpedo in water. Estimation of correct amount of lead depends on speed of target and target angle. Thumb rule explains the aiming allowance for ship vessels. The ship underway at sea takes a turn. (World War II period).

An aircraft in flight. The aircraft releases torpedoes at different angles in water simultaneously to attack the target area. Target ship maneuvers out of way. Torpedoes track in various directions through the water. (World War II period).
Rocket cars developed at the German Heylandt factory in Berlin-Britz, Germany
Momentary opening slate (in German) cites a new rocket car, the largest in the world, designed by German chief engineer Alfons Pietsch. Closeup of the liquid-fueled rocket car at the Heylandt factory in Berlin-Britz (Heylandt-Gesellschaft für Apparatebau mbH). The rocket engine is ignited and creates a huge flame behind the car. It travels for a while in the industrial yard of the Heylandt factory until the flame dies. (Note: At the beginning of 1930, rocket engineer Max Valier was given the opportunity to develop a liquid rocket engine at Heylandt in Britz. He was assisted by the Heylandt development engineers Alfons Pietsch, Walter Riedel and Arthur Rudolph, who built the rocket motor in a test vehicle called "hellhound" after Valier's accidental death in May, 1930.) Change of scene shows a rocket car of Max Dalier being refueled from a liquid oxygen tank. Next, the car, with "Heylandt" painted on its side, is seen with Max Valier at the controls, driving about the Heylandt factory grounds, propelled by a moderate thrust from its liquid fueled engine. It circles about the yard several times.
