It excludes turboprop and reciprocating engine powered airliners. It also excludes business jets and aircraft designed primarily for the transportation of air cargo. List of regional. PDF | Numerical simulation of a plane jet flowing out of a narrow slit is performed at different Reynolds numbers, based on solution of Navier–Stokes | Find, read and cite all the research you need on ResearchGate.  The location of asymptotic trend to analytical solution moves downstream with growth of Reynolds number. The study is the basis for further investigation of the instability development of instability in plane jets.

The jet plane model number would have had a fuselage 55 feet 17 m longer than the B and would have carried passengers in mixed class configuration and passengers in all economy configuration. Designations, which include a vehicle type symbol, jet plane model number optionally omit the basic mission letter if a modified mission letter is used instead as shown by the MQ-9A example. Pan American ordered these planes, when and as they did, so that they would be the operators of the "first-off" moxel line for each aircraft type. Although certified as Series s, s, s, etc. The is no longer operated by major airlines.

Boeing 7x7 aircraft production timeline, —present. First flight of the prototype aircraft took place on October 7, — the 32nd anniversary of the first flight of the original Learjet FAA certification was delayed, and finally granted in September , with the first customer aircraft subsequently delivered in mid Initially, delays in production resulted in frustrated customers and lost or delayed revenues.

Some customers' orders were delayed more than two years. By late , Learjet had delivered over Model 45s 40 of which were its improved version, the Model 45XR. Initially, numerous mechanical and electrical problems began appearing in the aircraft after delivery — including cracked windshields, problems with pressurization, fried power distribution panels, and inappropriate alarms.

These and other problems commonly forced Model 45 operators to ground their aircraft about once a month, limiting their use.

Problems came to a head in August , when the FAA discovered a defective fastener for the Model 45's horizontal stabilizer could break, sending the airplane into a fatal dive. The FAA grounded all Learjet 45s, across the nation, and they all sat on the ground for a month, while the manufacturer struggled to develop a fix and get it to aircraft in the field. By , Model 45 operators were said to have a "love-hate" relationship with the aircraft — appreciating its exceptional combination of performance, payload and economics, but frustrated by frequent maintenance problems, often grounding the aircraft, and difficulty getting prompt and adequate product support and parts.

It offers the operating economics typical of a "light" business jet, but the performance and comfort of a "mid-size" business jet. It has a 1,nautical-mile 3, km; 2, mi range at Mach 0. The plane was designed around a flat-floor cabin, [5] [6] with a non-circular cross-section for additional headroom. The Model 45 was Learjet's first "clean-sheet" all-new design since the development of the original Model Previous Learjet designs had used rigorous, extensive " fail-safe " structures in the wing and tail assemblies, with numerous wing spars providing a highly reinforced structure derived from the Swiss-designed P prototype fighter that was the original basis for the first Learjet [10] — but the Model 45, instead, used a lighter, less-robust structure, affording less cost in manufacture and lower aircraft empty weights, resulting in improved capacity, efficiency and some performance enhancement for a given amount of engine power , at a competitive price.

Outwardly, however, the Model 45 retained the traditional Learjet appearance, with its semi-swept wing, T-tail, sharp nose, and wrap-around windshield — while using engines and avionics similar to those in the Model It also incorporated two conspicuous modifications pioneered on earlier Learjets: the "delta fins" twin ventral fins, positioned to help stabilize the aircraft in flight, and help right the aircraft in a deep aerodynamic stall — and winglets upturned wingtips to reduce induced drag and improve stability.

Among other characteristics, the design has reportedly yielded the most benign stall characteristics of any "light" business jet to date as of At normal atmospheric conditions, zero-wind takeoff runway requirements range from 4, feet for a stripped, basic plane with a basic operating weight of 11, pounds to 5, feet for a fully equipped model, with auxiliary power unit and other upgrades 14, lbs.

However, the engine exhibits poor performance in high- density altitude situations such as takeoff from hot, humid or high-elevation airports , often resulting in long runway requirements. Engine power deficiency in high-density altitudes was largely resolved by the engine upgrade to the BR engine variant in the Learjet 45XR variant of the Learjet 45 — an engine upgrade which is also available as a retrofit to the older Learjet 45, and widely recommended.

An internal auxiliary power unit, for ground use, provides electrical and pneumatic power, permits easy starts, without ground power units, and enables aircraft cooling or heating while on the ground, without the engines operating.

However, the auxiliary power unit was initially optional, rather than standard, equipment. The wing has 13 degrees of wing sweep with a supercritical airfoil optimized for cruise flight at Mach 0. Though there are no leading-edge slats or wing fences , the wing has vortilons on the leading edge, to avoid spanwise flow , and small metal triangles on the leading edge to minimize airflow separation during flight at a high angle of attack.

The stricter Part 25 certification requires greater system redundancy, and requires that the airplane reliably meets the performance numbers published in the aircraft's FAA-approved Pilot's Operating Handbook POH. Dual-wheel, trailing link , main landing gear is provided, with digital nosewheel steering facilitating tight turns. The modified mission symbols are in general the same as the basic mission symbols, but add a few more letters.

The following modified mission symbols are defined:. However, this rule is rather often violated nowadays, e. KCA , retaining the number when a new designation in another series is assigned e. XA, T-6A. Also, sometimes numbers are skipped in one series because they are in use at the same time in another series e.

C was skipped to "avoid confusion" with T The first model always receives suffix "A" and subsequent series letters are to be assigned in strict sequence omitting "I" and "O" to avoid confusion with numerals "1" and "0". The series letter is actually a mandatory component of a conforming MDS, and therefore "plain" designations like "F" always designate the general type of aircraft and never a specific model. Of course, the sequence rule is often ignored and there are many designations with out-of-sequence suffixes e.

It is not well defined, which kind of modifications actually mandate the assignment of a new series letter. In the more recent past, even extensive modifications to an aircraft type have sometimes not led to a different series designation, e.

Because both modified mission and status prefix letters can appear to the left of the basic mission symbol, both groups of letters are distinct to avoid ambiguities.

The following status prefixes are defined:. There are three additional elements of a military aircraft designation, which are not part of the MDS proper, but which are nevertheless often encountered. These elements can be seen in the designations:.
