[1] [2] Pivotal is in the process of starting production of the BlackFly's successor, the Helix, at Pivotal's Palo Alto, California site. The BlackFly is the world's first ultralight fixed-wing , all-electric , vertical take-off and landing aircraft and the first ultralight EVTOL to be sold to customers. [ 1 ]
The FJ33 has a dry weight of less than 300 lb (140 kg), overall diameter of 18.36 in (466 mm), 38.43 in (976 mm) overall length, and produces between 1,000 lbf (4,400 N) and 1,800 lbf (8,000 N) static thrust.
The General Electric CJ610 is a non-afterburning turbojet engine derived from the military J85, and is used on a number of civilian business jets.The model has logged over 16.5 million hours of operation.
In February 2012, GE announced studies on a more efficient derivative of the GE90, calling it the GE9X, to power both the -8 and -9 variants of the new Boeing 777X.It was to feature the same 128 in (325 cm) fan diameter as the GE90-115B with thrust decreased by 15,800 lbf (70 kN) to a new rating of 99,500 lbf (443 kN) per engine.

Specific fuel consumption: 0.67 lb/lbf·hr (68.3·kg/kN·h) at maximum cruising speed; Thrust-to-weight ratio: 6.6; See also. Related development. General Electric CJ610;
The CJ-1000A is being developed for the Comac C919 narrow-body airliner with a thrust of 98–196 kN; 22,000–44,000 lbf. [2] It has a diameter of 1.95 m (6 ft 5 in) and a length of 3.29 m (10.8 ft), compared with the 1.98 m (6 ft 6 in) diameter and 3.32 m (10.9 ft) length of the CFM LEAP-1C. It uses a similar two-spool configuration to the ...
The PW 300 series has been developed in partnership with MTU who are responsible for the low pressure turbine. The first variant, the PW305A, has the following configuration and was designed with a core flexible enough for engines with take-off thrusts from 20 kN to 31 kN (4,500 to 7,000 lb): a single-stage fan driven by a three-stage low pressure turbine, supercharging a four-stage axial ...
Thrust is produced in the same direction, either way. For positive corona, nitrogen ions are created initially, while for negative polarity, oxygen ions are the major primary ions. Both these types of ion immediately attract a variety of air molecules to create molecular cluster-ions [ 14 ] of either sign, which act as charge carriers .
