The first manufactured object to achieve hypersonic flight was the two-stage Bumper rocket, consisting of a WAC Corporal second stage set on top of a V-2 first stage. In February 1949, at White Sands, the rocket reached a speed of 8,290 km/h (5,150 mph), or about Mach 6.7. [2]
Simulation of hypersonic speed (Mach 5) While the definition of hypersonic flow can be quite vague and is generally debatable (especially due to the absence of discontinuity between supersonic and hypersonic flows), a hypersonic flow may be characterized by certain physical phenomena that can no longer be analytically discounted as in supersonic flow.
The Heckler & Koch MG5 (in the development phase also known as the HK121) is a belt-fed 7.62×51mm NATO general-purpose machine gun manufactured by German firearm manufacturer Heckler & Koch.
The Gulfstream V (Model GV, pronounced "G-five") is a large, long-range business jet aircraft produced by Gulfstream Aerospace, derived from the previous Gulfstream IV.It flies up to Mach 0.885 (508 kn; 940 km/h), up to 51,000 feet (16,000 m) and has a 6,500 nmi (12,000 km) range.
The Avro Canada VZ-9 Avrocar is a VTOL aircraft developed by Avro Canada as part of a secret U.S. military project carried out in the early years of the Cold War. [1] [2] The Avrocar intended to exploit the Coandă effect to provide lift and thrust from a single "turborotor" blowing exhaust out of the rim of the disk-shaped aircraft.
In aerodynamics, the normal shock tables are a series of tabulated data listing the various properties before and after the occurrence of a normal shock wave. [1] With a given upstream Mach number, the post-shock Mach number can be calculated along with the pressure, density, temperature, and stagnation pressure ratios.
The rear control arm pivot points were lowered 1/2-inch on the upper end and 1/4-inch on the lower end for improved suspension geometry. In addition, quad shocks replaced the old-style traction bars and the rear anti-roll bar diameter increased to 0.79 inches (20 mm) compared to 0.67 inches (17 mm) in 1983.
A Lazair Series III with its bottom-mounted control stick. This one has been modified with a streamlined pod and windshield. The engines are the Rotax 185 9.5 hp two-stroke powerplants driving "biplane" propellers.
