One of the properties for liquid bipropellants is their hypergolicity. The required quantity for this purpose is ignition delay time (IDT). IDT is classified into two classes: physical and chemical. The chemical ignition delay time is the time interval between the contact of fuel droplet - oxidizer surface and appearance of the first flame. The best laboratory method for measurement of chemical...
