It is preferable to use established launch sites that offer tracking and VEHICLE/LAUNCH SYSTEM other vehicle processing services. Potential sites DESCRIPTION include areas such as the Churchill Launch Range, in northern Manitoba, Canada, and the Virginia The Canadian Arrow is a Space Flight Center, USA. 54-ft long, two-stage, three person sub-orbital rocket with the second stage PROPULSION SYSTEM doubling as an escape The Canadian Arrow first system. The first stage is stage uses a reproduction 33.5 ft. long and 5.4 ft. in WWII thrust chamber. diameter with four fins at Burning a mixture of alcohol the base for aerodynamic and liquid oxygen, this stability. motor will produce 57,000 Steering of the vehicle is pounds of thrust at sea level. accomplished using The engine is constructed of graphite jet vanes and low carbon steel with aerodynamic flaps on the propellant injectors made fins. The second stage (crew cabin) is 20-ft. long from brass. The first stage and 5.4 ft. in diameter at the base, and contains four propellants are fed to the jet-assisted-take-off type rocket engines for second engine using a pressurized stage propulsion. nitrogen gas system. This system is made up of two propellant tanks for fuel and oxidizer, topped by a The four solid rockets can be ignited at any point single composite construction high-pressure gas during the flight, including before launch, to initiate sphere. a zero altitude launch pad abort or an in-flight recovery sequence. The second stage of the Canadian Arrow is propelled by 4 jet assisted take-off type solid rocket For a zero altitude abort, the crew cabin will reach a engines. The four engines are ignited simultaneously height of 5,000 feet where it will deploy its 3 main just after stage separation. recovery parachutes. All of the hatches on the crew cabin can be explosively blown off for quick exit of The guidance system maintains correct attitude the vehicle. control using cold gas jets. For an in-flight abort, four extendable fin plates stored behind panels at the rear of the cabin will MISSION DESCRIPTION deploy to provide flight stability, similar to the type used on Russian launch VEHICLE ASCENT abort systems. The vehicle arrives at the launch pad 4 hours before The Canadian Arrow launch. After vehicle checkout, the propellants are sub-orbital vehicle is loaded, and chill down of cryogenic components designed for water begins. Final wet checkout is performed, and the splashdown recovery. flight crew enters the crew cabin approximately 30- Due to this requirement, min before launch. the launch site must have open water at least 100 ft After launch countdown, the propellant valves are deep, with a range opened, allowing the propellants to flow under footprint of 40 by 30 gravity into the combustion chamber. Ignition miles. This size of occurs, initially producing only 17,000 lbs. of thrust. footprint will The tanks are then brought up to full pressure, and accommodate in-flight the engine now builds rapidly to full thrust, lifting abort situations and the vehicle from the launch pad. Graphite vanes in range safety destruction the exhaust gas ensure a stable flight until enough of the first stage. Any speed has been built up to allow the aerodynamic coastal area is a potential fins to function. The first stage burns for just under one minute, until all of the propellant is exhausted.

Splashdown engine cutoff, the will occur in the water approximately 15 miles down occupants will range from the launch site. experience The crew cabin has a low center of gravity so that acceleration of no when floating on the water, the cabin will roll over more than 4.5 g. to a stable position with the hatches facing up. After At the edge of reorienting itself, inflatable floats are deployed on space, the second each side of the cabin to make the whole craft a very stage separates stable 'raft' on the water. The crew can now open the and ignites its hatches and stand up if they want to, while waiting engines, boosting for the recovery vessel. the velocity enough to reach 70 miles altitude. The pilot can use the cold gas jets to orient the second stage to provide the best window view for HARDWARE & TESTS the passengers. The Canadian Arrow team has constructed a full- scale engineering mock-up of the Canadian Arrow VEHICLE DESCENT AND LANDING rocket. After separation, the first stage follows a trajectory Hardware for the that carries it over 50 miles high.
