The P-800 Oniks (Russian: П-800 Оникс; English: Onyx), marketed in export as the Yakhont (Russian: Яхонт; English: ruby), is a Soviet/Russian supersonic anti-ship cruise missile developed by NPO Mashinostroyeniya as a ramjet version of P-80 Zubr.
The AL-21 is closely similar in technology to the General Electric J79 first flown in 1955, which was the first engine for supersonic flight, using a variable stator. [1]It is generally described as being in the "third generation" of Soviet gas turbine engines which are characterized by high thrust-to-weight ratios and the use of turbine air cooling.
The TJ100 engine entered service in 2003, [1] and is the most popular of PBS's turbojet engines as more than 1,000 engines have been sold to 40 countries worldwide. [2] The engine has been developed for unmanned aerial vehicles , including target drones , remote carriers, unmanned combat aerial systems , light experimental jet aircraft , and ...
k is the ion mobility of the working fluid, [19] expressed in A⋅s 2 ⋅kg −1 in SI units, but more commonly expressed with the unit m 2 ⋅V −1 ⋅s −1. A typical value for air at surface pressure and temperature is 1.5 × 10 −4 m 2 ⋅V −1 ⋅s −1). [19] As applied to a gas such as air, the principle is also referred to as ...
However, subsequent re-designs and the incorporation of more conventional systems resulted in the engine eventually meeting the NASA requirement of 700 lbf (3,100 N) thrust. To achieve the required thrust-specific fuel consumption , the EJ22 turbofan was designed as a three spool engine having a fan, two axial compressors and three expansion ...
Maximum thrust: 2,500 kgf (24.5 kN; 5,511.6 lbf) in takeoff mode (non-afterburning), 4,200 kgf (41.2 kN; 9,259.4 lbf) afterburning.; Overall pressure ratio: 15.43:1 ...
This proved very successful, allowing the Kurnass 2000 to exceed Mach 1 without the afterburners, and endowing a combat thrust-to-weight ratio of 1.04 (17 per cent better than the F-4E). This improved the sustained turn rate by 15 per cent, the climb rate by 36 per cent, medium-level acceleration by 27 per cent and low-level speed with 18 bombs ...
The results from the test firings of test motors SL-1 and SL-2 showed a maximum thrust value of 3.5 million pounds (15.7 meganewtons) and a burn time of 114 seconds. The firings used six tons of PBAN propellant a second, producing a column of white-hot fire visible in Miami 31 miles away. [ 8 ]
