REDDY TUBE

Reddy Tube is a hand-operated table-top shock tube, where the high pressures required for rupturing the diaphragm is generated inside the driver tube by pushing a hand held piston using only human force. Although the idea and execution is quite simple, this is the only instrument where shock waves of desired strength can be successively generated repeatedly.

Inner diameter	29mm	Diaphragm rupture pressure	Up to 7 bar (Manual)
Driver tube length	400mm	Initial driven side pressure	200 – 760 mm of Hg
Driven tube length	600mm	Primary shock Mach number	1.3 – 2.0
Diaphragm material	Paper 95 gsm	Material of construction	Stainless steel

SUPERBULL

SUPERBULL is a novel artificial insemination gun in which the Reddy tube is incorporated with the existing mechanism of artificial insemination in livestock. SUPERBULL increases the overall efficiency of the system and improves the rate of conception. The syringe of the conventional artificial insemination gun is replaced by the Reddy tube which sprays the semen into the uterus and reducing the probability of sperm mortality before conception. SUPERBULL has a superior success rate of about 50% when compared to the success rate of conventional artificial insemination gun which is about 30%.

Inner diameter	2mm	Number of cartridges	5 (can be purchased separately)
Overall length	610mm	Features	1. Durable
Weight	90g		2. Damage-resistant
Material of construction	Stainless steel		3. User-friendly

REDDY TUNNEL

The Reddy shock tunnel poses an economical and easily manufacturable option for basic hypersonic research at the university level. It is hand operated and fits onto the top of a table. The primary shockwave in the shock tube portion (Reddy tube) is generated using only manual force. This device can be used to conduct basic aerodynamic research for engineering students.

Inner diameter	29mm	Max. model dimension	50mm
Driver tube length	400mm	Flow Mach number	6.0
Driven tube length	600mm	Max. effective test time	300 microseconds
Diaphragm material	Paper 95 gsm	Material of construction	Stainless steel

HIGH-SPEED VALVE

The high-speed valve is an ideal long term solution to replace metal diaphragms in conventional shock tube systems. The high-speed valve developed and patented by MACHSTAR has very good repeatability and durability. This valve has a very quick opening time even for a large diameters of up to 80mm. Various customizations are available for the valve as per customer requirements

Exit diameter	20mm – 80mm	Opening time	Less than 2 milliseconds
Operating pressure	2 bar – 60 bar	Actuation type	Electropenumatic /Pneumatic
Operating temperature	20 – 50 deg Celsius	End connection	Threaded/Flanged
Operating medium	Air/inert gas	Material of construction	Stainless steel
