Apropo, ha mar loszer meg loveg - ez meg a 2019-es L52-es rekord idejebol:
DM’s work will include four main areas as far as range extension is concerned.
The new charge system will aim at increasing muzzle velocity by 5-8%; work is underway, Rheinmetall having unveiled a Top Charge available both for 52 and 39 calibre chambers which ensures a range increase of 6 km, up to 46 km, with a 52-calibre barrel, muzzle velocity reaching 1,000 m/s versus 945 m/s of Zone 6 modular charges, while in the 39-calibre configuration range increase is of 3.4 km, up to 27.4 km, with the V0 stepping up from 805 o Zone 5 charges to 900 m/s.
Leveraging this development, RDM’s R&D department is at work on propellant to further improve performances, while the following step will be to obtain similar results with a new modular charge system, which would provide extended range while maintaining full flexibility.
The second and third areas of development both concern the rocket motor, the aim being to increase its impulse, which should add a further 5-8% range increase to a VLAP projectile. RDM is also looking at the reduction of the rocket motor mass, a measure that should bring with it the highest effect, as estimates call for a range increase of 10-14%; the mass reduction might however be traded off with lethality.
Finally an improved drag profile should bring in a further 4-6% range increase; trials were made using the Gerald Bull form factor. According to RDM there might still be some space for improving aerodynamics, working both on the round case itself as well as on the Base Bleed, some of those improvements having already been adopted on the company M9 series of artillery ammunition.
According to RDM forecast, adopting the three first options the range of the ER-VLAP round should exceed 70 km, while adding the fourth element of improvement it would reach 75 km. As for lethality, the ER-VLAP should have a lethal effect against personnel similar to that of a standard HE round.
Ha ezekkel az ER VLAP es ujabb csodakkal rafekszenek az L60-ra, szerintem vidaman 100km vagy felette lesz az uj rekord...
