Mach Five was designed by Mitsuki Nakamura, who was the art director of Tatsunoko Production, which produced the 1967 TV anime series. [1] [2]The initial plan was to keep the original manga [a] design for the anime production, but it was decided to redesign the car, and Nakamura, a car enthusiast, was entrusted with the task. [3]
The Mach number is named after the physicist and philosopher Ernst Mach [3] according to a proposal by the aeronautical engineer Jakob Ackeret in 1929. [4] The word Mach is always capitalized since it derives from a proper name, and since the Mach number is a dimensionless quantity rather than a unit of measure, the number comes after the word Mach; the second Mach number is Mach 2 instead of ...
In aerodynamics, a hypersonic speed is one that exceeds five times the speed of sound, often stated as starting at speeds of Mach 5 and above. [1] The precise Mach number at which a craft can be said to be flying at hypersonic speed varies, since individual physical changes in the airflow (like molecular dissociation and ionization) occur at ...
Mach 5 or variation, may refer to: Mach 5 (speed), a mach number representing the delimiting speed separating supersonic speed (below Mach 5) from hypersonic speed (above Mach 5), 5 times the speed of sound. Mach Five (Japanese: マッハ号), a racing car in the Speed Racer franchise. Mach-V, an alias of the Marvel Comics character Abner Jenkins.
Hypersonic flight. Hypersonic flight is flight through the atmosphere below altitudes of about 90 km (56 mi) at speeds greater than Mach 5, a speed where dissociation of air begins to become significant and high heat loads exist. Speeds over Mach 25 have been achieved below the thermosphere as of 2020. [citation needed]
Speed Racer, also known as Mach GoGoGo (Japanese: マッハ GoGoGo ゴーゴーゴー, Hepburn: Mahha GōGōGō), is a Japanese manga series written and illustrated by Tatsuo Yoshida. It was originally serialized in print in Shueisha 's 1966 Shōnen Book. It was released in tankōbon form by Sun Wide Comics and later re-released in Japan by ...
Supersonic speed is the speed of an object that exceeds the speed of sound (Mach 1). For objects traveling in dry air of a temperature of 20 °C (68 °F) at sea level, this speed is approximately 343.2 m/s (1,126 ft/s; 768 mph; 667.1 kn; 1,236 km/h). Speeds greater than five times the speed of sound (Mach 5) are often referred to as hypersonic.
First flight. 26 May 2010. Retired. 2013 [citation needed] The Boeing X-51 Waverider is an unmanned research scramjet experimental aircraft for hypersonic flight at Mach 5 (3,300 mph; 5,300 km/h) and an altitude of 70,000 feet (21,000 m). The aircraft was designated X-51 in 2005. It completed its first powered hypersonic flight on 26 May 2010.
