In performance calculations, airliner manufacturers use a density of jet fuel around 0.80 kg/L (6.7 lb/US gal; 8 lb/imp gal). Specific cases are: Bombardier Aerospace: The Challenger Multi-role Aircraft is a special mission variant of the Bombardier Challenger 650 business jet platform. Bombardier bases performance on the use of fuel with an ...
By 2019, fossil jet fuel production cost was $0.3-0.6 per L given a $50–100 crude oil barrel, while aviation biofuel production cost was $0.7-1.6, needing a $110–260 crude oil barrel to break-even. [19] As of 2020 aviation biofuel was more expensive than fossil jet kerosene, [1] considering aviation taxation and subsidies at that time. [70]
Aerospace engineering is the primary field of engineering concerned with the development of aircraft and spacecraft. [3] It has two major and overlapping branches: aeronautical engineering and astronautical engineering. Avionics engineering is similar, but deals with the electronics side of aerospace engineering.
The FBISE was established under the FBISE Act 1975. [2] It is an autonomous body of working under the Ministry of Federal Education and Professional Training. [3] The official website of FBISE was launched on June 7, 2001, and was inaugurated by Mrs. Zobaida Jalal, the Minister for Education [4] The first-ever online result of FBISE was announced on 18 August 2001.

Military fuels such as T-1pp, [19] T-8V (aka T-8B) and T-6 are specified by GOST 12308. [18] Icing inhibitors are specified by GOST 8313. [ 18 ] Some researchers refer to T-6 as "ram rocket fuel"; [ 20 ] others have patented a method used to produce T-1pp from a mixture of T-6 and RT, [ 19 ] the latter of which has been characterized as ...
Consider the motion of an element of mass in position -z, x in the direction of the y-axis, i.e. into the plane of the paper. If the roll rate is p, the velocity of the particle is: v = − p z + x r {\displaystyle v=-pz+xr}
